Title: Front brake issues. Post by Zeke342 on 02/26/12 at 19:53:34 So I'm still in the slow progressing process of rebuilding my 1997 savage.. recently got all the body parts back on excluding the carburetor and when I went to use the front brake I couldn't get it to do anything at all. No pressure in the handle and the front brake doesn't activate at all. So we drained the bit(resevoir?) with the brake fluid in it and bled the brake but nothing changed when we did this. The bike has not been ran in 5+ years due to my uncle leaving it next to a trailer after he bought it off us years back.. We looked online at other sites(couldn't find anything on here) and some people suggested disconnecting the hose from the resevoir and placing my finger over the hole and pumping the brake.. but I wasn't sure what I was looking for and nothing happened. If pictures or anything I can do answer questions will help please let me know.. I'm very eager to get this work in progress running again >.< Also, on a side not.. we can't figure out how to reconnect the carburetor after removing it for a rebuild :-[ we have it on the bike but two hoses (i think) come off the carburetor and connect to other sections of the bike.. and I don't want to screw something up by getting the hoses mixed up.. a diagram or if it's easily explainable would help a ton and I'd greatly appreciate it :) After these two issues are sorted and assuming the rebuild worked the bike should finally be finished and ready to ride ^_^ |

Title: Re: Front brake issues. Post by verslagen1 on 02/26/12 at 20:40:46 If the reservoir had fluid in it at the beginning, that was not the cause of your brake not working. More likely the caliper needs rebuilding. A good hard squeeze may have broken it free. But now that you have now fluid in it, take it a part and clean it. Here's the carb tech post for the hose routing... http://suzukisavage.com/cgi-bin/YaBB.pl?board=tech;action=display;num=1098869040 |

Title: Re: Front brake issues. Post by Zeke342 on 02/27/12 at 05:24:18 Okay, I'll give that a shot tonight that thank you :) Thanks also for the diagram, made it simple lol. Also, what SHOULD the rubber diaphragm in the reservoir look like? Mine looks nothing at all like the one in this posting http://suzukisavage.com/cgi-bin/YaBB.pl?num=1177184106/13 Mine is all pushed downward and looks warped. |

Title: Re: Front brake issues. Post by drums1 on 02/27/12 at 11:36:20 That rubber gasket should sit flat. If it's warped, chances are it got some oil on it at some point. Pull it out and see if it lays flat. It could have gotten sucked down in there as the fluid goes down. If it stays warped, it needs to be replaced. If it got oil soaked, then all the rubber parts in the brake system need to be replaced. Oil tends to make rubber turn gummy, and it will warp. Hopefully, that is not the case here. If it lays flat, then just fill up the master and bleed the system, keeping the master full as you go. |

Title: Re: Front brake issues. Post by Zeke342 on 02/27/12 at 12:53:59 No lol... it's very warped. when it's put into the master cylinder it just pushes the fluid out like its over filled. Definitely needs to be replaced.. I'll take the caliper apart this afternoon and see if anything else is damaged. Thanks guys :) |

Title: Re: Front brake issues. Post by drums1 on 02/27/12 at 15:15:12 Ya, you need to replace that gasket, if not the whole master cylinder. Also the rubber brake hose/line, and the caliper. Caliper may be able to rebuild with new parts, might be almost as much money as a new caliper. Or a good used one. Anything that has rubber parts in it. And then you need to do a good flush and bleed. Then you should have brakes again. Good luck. |

Title: Re: Front brake issues. Post by Zeke342 on 03/01/12 at 12:43:18 Ok so it turns out no oil got into the master cylinder... I just wasn't aware it appeared to be sucked down.. I just popped it into its correct form and it looks alright. Took the caliper off and everything APPEARED alright.. but still no pressure in the brake lever. Could the piece in the master cylinder (listed as #2 in this link http://www.cheapcycleparts.com/model_years/4007-suzuki-1997-savage-ls650p/assemblies/117823) need to be replaced for one reason or another? Any suggestions would be great :) |

Title: Re: Front brake issues. Post by Serowbot on 03/02/12 at 09:27:51 If it were me,... I'd pull the caliper,..remove the master cylinder cover,.. then gently compress the brake piston using a c-clamp (watch the master fluid level while you do this, it will rise and may overflow)... Then put the master cyl. cap back on, remove the clamp, and gently squeeze the lever (may take a few pumps, but go slow),.. and see if the piston pushes out... If it won't push out after several pumps, something is wrong... If it does pump,.. put it all back together and pump the lever a bunch of times to pump it up... Bunches!... |

Title: Re: Front brake issues. Post by justin_o_guy2 on 03/02/12 at 19:31:42 Sounds like a good plan from here.. |

Title: Re: Front brake issues. Post by Serowbot on 03/02/12 at 21:17:05 Great minds, JOG... great minds, think alike... ;)... ... ('course,... so do retarded sheep)... ...so that's a wash... :-?... But,.. we're simpatico... either way... :)... A. Most basic tests B. Most simplest/cheapest solution C. Then,... if it ain't the easy stuff,.. feel safe in moving on... ... but, never go deep, 'till you've scanned the surface... Nothing makes you feel lower,.. than, seeking a big solution, to a little problem... (I learned my lesson on my first Metro... when I tried everything to get her started, and found no compression, and decided she needed a new motor... Then, without even looking, my backyard mechanic buddy, told me I'd been trying so hard, for so long, that I had washed the cylinders of their oil compression seal with raw gas, and lost compression... He oiled cylinders and cleared a small bug from the throttle body... and she ran perfect)... He charged me $20 for about 15 minutes.... I gave him $40.... Not my first time,... but the one that taught me my lesson... Point is,.. a tiny bug made think I needed a new motor.... Excuse my rambling... it's not always the simple thing,... but often as not... Best luck, Zeke... keep us apprised... |

Title: Re: Front brake issues. Post by Zeke342 on 03/03/12 at 11:14:20 Tried what you said and nothing happened... When we compressed that part of the caliper (technical name lol?) it cause the brake fluid in the master cylinder to bubble but it didn't over flow (it's probably just low on fluid).. Everything looks in order so I'm at a total loss >.< I'm contemplating just going flinstone to bring the bike to a stop when I'm riding lol. |

Title: Re: Front brake issues. Post by justin_o_guy2 on 03/03/12 at 12:31:21 It bubbled because the line was full of air, be my guess.. Have you cracked the bleeder & put a hoe on it into a container & just walked away? If the fluid startd dropping, make sure & keep it full. |

Title: Re: Front brake issues. Post by RidgeRunner13 on 03/03/12 at 12:42:57 One more time: Put a clear hose long enough to reach the master cylinder on the slightly opened bleeder screw. Hold the loose end of the hose in the m/c reservoir under the fluid level & squeeze the brake lever until you have a solid stream of fluid in the hose. Do not let the free end come out of the fluid while you're doing this. Once there are no bubbles in the hose, close the bleeder & using a rag remove your bleeder hose, first at m/c, then at bleeder. If you do this right, you won't have a mess to clean up & you will have the firmest brake ever. Works every time for me..... 8-) |

Title: Re: Front brake issues. Post by Zeke342 on 03/03/12 at 13:57:38 Awesome, got it working great :D after we get it on the road and such should I take it easy on the brakes for awhile? Probably should anyways considering the bike hasn't been started in a very long time >.< |

Title: Re: Front brake issues. Post by justin_o_guy2 on 03/03/12 at 14:19:01 YOu changed the oil? Drain the carb bowl? Probably nothin to drain.. |
|
Title: Re: Front brake issues. Post by Zeke342 on 03/03/12 at 14:32:51 Yup fresh oil, spark plugs, brake fluid, and carb was rebuilt (hopefully properly) so hopefully we get the tank back on and start it for the first time in who knows how long tomorrow lol. |

Title: Re: Front brake issues. Post by justin_o_guy2 on 03/03/12 at 18:26:15 Make sure the battery is fully charged. & dont forget to use Prime for gettin the bowl filled up. & Good Luck! |

Title: Re: Front brake issues. Post by Zeke342 on 03/03/12 at 19:23:40 Brand new battery.. the old one was.. a lost cause lol. And no idea what Prime is or what "getting the bowl filled"... I come from sport bikes to cruisers and this is my first project unfortunately >.< |

He was referring to the Prime setting on the petcock. You should put it on Prime to let gravity cause some fuel to go from the fuel tank to the carb bowl until the float should stop the flow of fuel. After 30 sec or so, you could switch it back to ON and it should work as designed as long as your petcock vacuum line is connected as well. ;D |
