Title: brakes woes Post by JBK on 04/15/14 at 20:40:43 So bikes back together. Only have 2 small problems. No front or rear brakes. I cleaned the old fluid out (13 yrs old) and put everything back together. bled according to this site. But got no pressure to the pads. Fluid is making it to the caliper. But nothing happening. Now the back. Left alone but on the pedal I get no return after pressing down. The spring is on right. But I noticed it is loose fitting on the rod. What's making it not return? |

Title: Re: brakes woes Post by verslagen1 on 04/15/14 at 21:13:29 how did you bleed the fluid? and there's a spring on the foot pedal that doesn't get put on correctly. |
|
Title: Re: brakes woes Post by Cloudy on 04/15/14 at 21:51:39 Also check that on the front the pads are on EITHER side of the disk, if they arn't, no brake's. How do I know this? New tire on a CBR1000f, I refitted the wheel, test ride......... Take about pucker factor!!!!!! |

Title: Re: brakes woes Post by Cloudy on 04/15/14 at 22:57:30 just reread your post. You didn't remove the wheel did you? just disregard my ramblings then. Sorry. |

Title: Re: brakes woes Post by Dave on 04/16/14 at 03:45:24 For the back brake.....make sur the front pedal is free to move and not all gummed up or rusty (do the same for the shift pedal while you are checking things). The pedal locations are right up in the path of the spray from the front tire and all kind of junk gets thrown at them. If the pedal is stuck and won't return the brake won't work. There is a spring at this pedal that is supposed to be hooked over the peg mount and it often slips off if you have removed the peg. Check the cable and make sure it is working freely, and finally you need to check the brake arm on the hub. The shaft that passes through the brake backing plate should be lubed and working freely. You can take the nut off the threaded end of the cable and pull the cable out, and work the parts to see what could be haning up. For the front brake - it is sometimes hard to get things bled as the air wants to move up the brake hose as the same time you are trying to push it down. Not sure of the process you are using - when I did mine I used a hand vacuum pump to pull the fluid down from the master cylinder and kept pumping until I got fluid without bubbles. I then started to bleed the system by pumping the master cylinder until I had some resistance at the lever - then opened the bleed screw and let the pressure off as the flud ran out. Then close the bleed screw and pump again.....and I kept doing this until I was sure all the air was out and I had a good lever pull. |

If it's not installed right the pedal wont return. If you had the foot peg bracket on that side off for any reason the spring probably popped out of place. Mine did . I had to fiddle around for a while before I figured out how to get it hooked back on so it worked. |

Title: Re: brakes woes Post by justin_o_guy2 on 04/16/14 at 08:02:22 Did you remove the caliper or just drain fluid? If you pulled the caliper, tell us what all ya did. Hard to find the mistake in a post that just says "I did everything right".. |
|
Title: Re: brakes woes Post by JBK on 04/17/14 at 18:00:17 The pic on bike bandit shows the spring on the outside of the pedal. Is that right? Seems like it only fits on the inside. Am I missing something? |
|
Title: Re: brakes woes Post by oldNslow on 04/17/14 at 19:10:20 If by outside you mean on the side of the brake pedal closest to the foot peg that's right. The diagram may be a little confusing because it doesn't show the footrest bracket. If you have a Clymers Manual there is a diagram on page 325 that shows the relationship of the parts better. It even shows how the spring is installed. The pedal pivots on a stud on the back side of the footrest bracket. The spring fits over the part of the pedal that slides over the stud closest to the footrest bracket, The side of the spring without the hook bent into it is basically up against the BACK of the footrest bracket. The hooked end of the spring hooks over the end of the pedal near where the brake cable is attatched. The straight part of the spring needs to be BEHIND the hollow boss on the frame that the long bolt( the front engine mount bolt actually) that comes from the other side of the bike and holds the front of both peg brackets on. I hope that makes sense - or that someone can post a picture. |

Title: Re: brakes woes Post by JBK on 04/18/14 at 04:37:18 Thats exactly how mine is mounted. Still got no return. |
|
Title: Re: brakes woes Post by oldNslow on 04/18/14 at 05:07:04 Disconnect the cable from the pedal. See if the pedal snaps back up when you depress it. The tension of the spring holds the pedal up. If it doesn't it's not in right, or the pedal is binding on the stud that it pivots on. If the pedal works ok then disconnect the end of the cable attatched to the brake arm at the rear wheel and push/pull on the cable. make sure it is free. Same with the brake arm. Move it back and forth with the cable off and make sure it's free. With the cable disconnected from the arm and the pedal you should be able to determine where the problem is. |

Title: Re: brakes woes Post by Dave on 04/18/14 at 05:14:37 oldNslow: Yep....absolutely. The rear brake cable needs to be disconnected from the brake arm....and things need to be wiggled to see what is hanging up. Something is in a bind.....needs cleaned and lubed. JBK needs to get his hands dirty this weekend....... |

Title: Re: brakes woes Post by JBK on 04/19/14 at 15:02:37 alright took it apart and put it back together a little more carefully this time.....got rear brakes now. since thats done, thought i'd fire her up for the first time in months. all it will do is turn over. battery is pretty weak with being attached to charger. its got fuel getting to the carb. no leaks. one thing is white smoke trying to come out the exhaust. tried on primer, res, choke in and out, and throttle open. i did do the oil plug fix over the winter, but everything went back together fine. could the batt be all but dead? btw the fuel is new, drained all old months ago. |

When all else fails, try a shot of starter fluid in the carb. A couple second shot and let it evaporate a little. If it fires up you've eliminated spark and electrical issues. Could be a stuck float or gummed up if it has been sitting with old gas in the carb. Battery could definitely be an problem if it is weak. |

Yup. Check that first. Make sure it is fully charged and not on it's last legs. Very common,well known issue with these bikes . Starter will crank the engine but if the battery is weak there is not enough juice left to fire the plug. |

Title: Re: brakes woes Post by JBK on 04/19/14 at 16:52:38 popped the tops on batt. juice was low. with batt hooked to charger, bike turns over strong. take off and you have to have your nose up to the headlight to see any kind of light. so gonna hook up a new one and start there. also, should there be any concern about the little bit of white smoke? |

What kind of charger - how may amps? Hooked to a charger I would have expected it to start. Just like jump starting a car with a dead battery. Unless it's just a trickle charger. 1or2 amps. That still probably isn't enough current, especially if the battery is toast. Quote:
Has the bike run since you put it back together? I think the next simple thing is a shot of starting fluid into the intake side of the carb like S-P suggested. See if you can get it to fire at all. I wouldn't worry too much about the smoke till it's running. |

Title: Re: brakes woes Post by JBK on 04/19/14 at 20:55:54 charger being my car. without it the bikes batt is all but dead. lights past dim and no turn over. with everything seems strong. and today is first time bikes been turned over since dec. my dumb self didnt take care of the batt as i should. |

Jumping from a car battery, assuming everything else (spark, fuel etc) is OK I think it should have started. Did you try some starting fluid so see it it would fire at all? Did you check the valve clearances after you put the head cover back on after fixing the head plug leak? |
|
Title: Re: brakes woes Post by JBK on 04/20/14 at 20:41:18 havent tried starting fluid yet. and didnt even cross my mind to check valves. would that make a bike not crank? |

http://suzukisavage.com/cgi-bin/YaBB.pl?num=1325991352 Could make it hard to start, or not start at all if they are far enough out of adjustment. Anyway It looks like you have looked at everything else. It's worth checking IMO, especially since you had the head cover off. |

Title: Re: brakes woes Post by JBK on 04/21/14 at 17:41:28 ive adjusted them before so im familiar with them. ill pop the tank off and check em. po is a mechanic and he thinks fuel is not getting t owhere it needs to to fire engine. about to clean up the carb for starters |

That's the reason for trying a blast of starter fluid into the carb intake. If the bike will run - even for a few seconds- on that, you've confirmed that it's a fuel problem. |

Title: Re: brakes woes Post by JBK on 04/21/14 at 21:09:46 no go on the starter fluid. made no change. did notice lights on bike dimmed greatly when i tried. even when hooked up to car. im running out of options here |

Not really. I think you might be just overlooking something simple or assuming something is OK when it's really not. For the bike to run you need: 1. A battery that is capable of cranking the engine fast enough, and that also has enough juice while running the starter motor to fire the spark plug. 2. A combustible fuel/air mixture being introduced into the combustion chamber. 3.The valves have to be open when they should be and closed when they should be. They have to be CLOSED at TDC on the compression stroke. 4: Adequate compression - no broken rings, piston etc. which I'm pretty sure is not the problem here. If those conditions exist the engine has got to run. I think you need to verify that all the things you think are OK are actually OK, starting with the battery. I don't know of any other way to figure this out except rechecking the things I mentioned above until you are positive the you've eliminated each one as the issue. |

Title: Re: brakes woes Post by JBK on 04/22/14 at 11:21:59 I'll start with battery, then carb, then valves. Will update as I go. |
|
Title: Re: brakes woes Post by JBK on 04/23/14 at 17:33:33 New battery in. Still nothing. Turns over strong. On to carb. |

I'd double check the plug first. Pull it out, ground it to the head, crank the motor and make sure you see a good spark. You don't know the plug is firing till you SEE that it's firing. If it is, then put it back in and try the starter fluid. |

Title: Re: brakes woes Post by old_rider on 04/23/14 at 19:28:35 After you clean the plug... check for spark..got power? Make sure your petc0ck is off, remove the tube from the carb...turn on your petc0ck..fuel? Put the tube back on, turn on your petc0ck....open the drain on your fuel bowl... fuel? Tap your fuel bowl or take it off and see if the float needle drops ( it could be sticking) Safety switches.... clutch, kickstand and neutral.... After that i'm lost.... only thing left would be the decomp....that I can think of.... Here is to hoping you find it.... |
|
Title: Re: brakes woes Post by JBK on 04/23/14 at 20:22:54 Carbs cleaned thoroughly and still nothing. Got fuel coming from petcock and floats not sticking. So I'm guessing it's getting fuel where needed. Will try plug next. Although it's fairly new. Then valves then retrace my electrical. It ran fine before the teardown. So hoping I put something back wrong. |

Title: Re: brakes woes Post by JBK on 04/25/14 at 04:16:24 Haven't had time to pull tank so pulled plug wire and hooked up extra plug and got no spark at all. So that means what? |

When you have time to pull the tank off make sure you didn't inadvertently disconnect one of the small wires that connect to the coil while you were working on the head plug leak. |

[/quote] EDIT: I just looked at my bike. If you get down on your knees and look up under the left front corner of the tank you can see the coil wires without taking the tank off. Even if they are still connected it wouldn't be a bad idea to to pull them off and make sure the connectors are not loose/corroded. |

Title: Re: brakes woes Post by justin_o_guy2 on 04/25/14 at 10:26:25 Oncet upon a time one of our members reported riding home, parking, got off, went in the house, came out an hour or so later & Dead Bike,, Nuthin, mang.,. The connector under the tank had vibrated loose & it Juuust got him home,, \If youre gonna pull the tank, leave the speedo cable on the tank, be aware of the O-ring on the transmission end. IF they fall they tend to jump behind the starter, so, cover that hole first,And, before ya pull the tank, prepare a place to lay it down first & make it raised up enough so the speedo cable isnt bent too hard, Sometimes gettin the petcock past the frame is almost impossible. Lift the rear of the tank & slap it to the side as ya lift,, Its sure liable to scratch the fram. OR, Drain the tank & pull the p[etcock,,Now is a good time to put a Raptor on. |

Title: Re: brakes woes Post by JBK on 04/25/14 at 17:07:07 Yea that would be egg all over my face. What's the green/Orange wire? Cause I didn't have connected. Fired up immediately. Appreciate all the help. Learned alot. Didn't even have to pull tank. Just seat. Gonna ride now. Will post pics. |
