Title: Rear Drum Break Sticking? Post by Wake51 on 06/03/12 at 20:18:47 I took the bike out yesterday and noticed that the rear break pedal felt a bit... odd. Well at the second stoplight I came to the bike had more trouble than normal taking off the line. I realized the rear drum break was sticking and providing resistance to the rear wheel. I lifted up on the break pedal with my boot and it disengaged. I rode to the nearest gas station and pulled over to see what the problem was. By this point once I pressed the break, it wouldn't disengage at all. Lifting up on the pedal yielded no response. If I pushed the pedal down, it would go until I heard a click. The only way to get the break to disengage was to back the adjuster nut out on the cable until the break released. Once it was adjusted enough to release, the break pedal did nothing when pressed. I played with the adjustment a bit which was the only thing the brake was responding to. Couldn't get it to disengage with the nut turned in on the cable, couldn't get it to engage with the nut turned out on the cable to a point where it would let the wheel spin freely. Any ideas? The bike has 12,5XX miles and the drum pads seemed it good condition last time I had the wheel off, can't imagine they would ever need replaced anyway. |

Title: Re: Rear Drum Break Sticking? Post by verslagen1 on 06/03/12 at 20:24:06 are the pedal return spring and the brake arm return spring on correctly? the front spring is quite often not on right. |

Last couple of times I put the rear wheel back on the brake has worked fine. Including the last. This seems to be a recent development not resulting from taking things apart. The front pedal has never been apart. Could some of this incur misplacement from wear and tear? |

Agreed. Certainly not a bad thing. The only problem is finding a friend to help put it back on as my hands aren't numerous enough to do it. Had I not recruited my roommate to do it 2 other times then it wouldn't cost me a couple o' beers... Right now I have some good stuff in the fridge, should I just take it "somewhere"? :D I suppose I was wondering if anyone had a diagnosis of what it would be within the break given the pads generally don't wear down this early as to get a head start on part ordering. A suggestion from local family members suggested worn springs or a worn out cam, but suggested the unlikeliness of such parts being worn yet. |

Title: Re: Rear Drum Break Sticking? Post by rfw2003 on 06/04/12 at 00:39:37 when you try using the brake pedal does it move the brake cam at all? if not you may have a seized cable or melted cable causing your issue. That is what it is sounding like to me since at first you said you could pull the pedal up to free it then the next time you were not able to pull the pedal up and now can only release it by backing the adjusting nut off at the brake cam itself. The Brake cable could have shaken loose somewhere and came to close or in contact with your exhaust and caused this exact issue. Just my 2 cents for something to check. R.F. |

Title: Re: Rear Drum Break Sticking? Post by Dave on 06/04/12 at 05:00:38 You need to do a little investigation. Loosen the adjuster at the rear wheel and see if the brake arm on the wheel is free. If the shaft is corroded or dry it may be sticking. The brake cable could also be dry and sticking - as could the front pedal. It sounds to me like you need to take the brake system apart, clean and lube the moving parts. |

Title: Re: Rear Drum Break Sticking? Post by 360k+ on 06/04/12 at 07:32:06 I agree with Dave. First figure out what is causing the stick, then focus on that part of the overall brake system. It looks pretty easy to isolate the 3 groups. |

Title: Re: Rear Drum Break Sticking? Post by justin_o_guy2 on 06/04/12 at 07:43:18 Good call Dave,, Yea,, he is dead on there,,Isolate the possible causes & check them out individually. You may need a cheater to engage the brake w/o the pedal. A deep socket & extension makes a decent cheater in places where a guy just needs a bit more Oomph. I use 1/4 drive stuff on allen wrenches all the time.. If you do wind up going into the brake area, make sure you dont breathe any of that dust. One man can reinstall the rear wheel, |

Or at least one man and a midget. Off topic... looking thru the shop manual I noticed there are "cushions" in the rear wheel, I presume to help smooth the thump. These look replaceable. Are they hard rubber or what? |

Title: Re: Rear Drum Break Sticking? Post by justin_o_guy2 on 06/04/12 at 08:21:24 Theyre pretty stiff, but their job is pretty tuff, too. Yea, theyre replaceable , but they dont need replaced, generally.I saw some slack in mine & cut some strips of inner tube & shimmed them up a bit. It takes some planning, getting everything set up where ya need it & some coordination & ability to see whats not fitting & what its gonna take to get it going. A rolling stool is important, because feet go under the tire to lift & position it. Getting the spacer in on the belt side needs to happen early. |

[/quote] Way back in time (1973) the Suzuki dealer I worked at used to take the rear hubs on the TM racing bikes apart - then pour an epoxy rubber into the hub to fill the voids between the rubber blocks and the hub. When the sprocket hub was replaced the excess rubber oozed out and was cleaned up. When the epoxy rubber set up there was no more play - but you still had the cushion. |

Title: Re: Rear Drum Break Sticking? Post by skeebo on 06/04/12 at 08:36:05 The guy I bought my bike from had the same issue but rode a little to long...... Rear hub was seized when I got it, has a nice color now.... |

Title: Re: Rear Drum Break Sticking? Post by 360k+ on 06/04/12 at 08:55:31 Wow, that golden hub is a nice touch! |

Title: Re: Rear Drum Break Sticking? Post by Boofer on 06/04/12 at 10:04:59 Check and lube the activation parts and spring as stated. Then check the arm on the hub to see if it is slipping around the pivot. Then open it up to check if the cam is going past the point of no return for some reason like a worn or broken brake shoe. That's all I got. :-/ |

Title: Re: Rear Drum Break Sticking? Post by 360k+ on 06/05/12 at 16:23:45 I was out looking at my scoot rear brake and realized that the PO had put the pedal bracket back on with the pedal spring prong on the wrong side of the frame cross rod. This means that the pedal had no spring return at all and was solely dependent on the spring on the cable end to pull the lever up. I kept thinking I was hearing a "jingling" sound when I rode. I don't think this would be the cause of Wake51's problem, but it sure wouldn't help either, so make sure the spring prong is behind the cross rod on the frame and asserting "pull up" on the brake pedal. |

Title: Re: Rear Drum Break Sticking? Post by Wake51 on 06/14/12 at 23:16:06 Sorry for a late response to all the advice. I'll tear the break system apart this Saturday, I slated the day since I finally have time. I'll inspect it from pedal to pad and see where the issue is taking all suggestion along the way when I find the culprit. That IS indeed a nice golden hub... is it functional? And I don't mean in the sense of luring in chicks! 8-) I'll post what problem I find, a bit curious at 12,xxx for a drum in my opinion. Hopefully it will help someone else troubleshoot. |

Title: Re: Rear Drum Break Sticking? Post by greenmonster on 07/16/12 at 10:45:02 Did you find the problem? I ask since I'm experiencing something similar. |

Title: Re: Rear Drum Break Sticking? Post by HighME32 on 11/16/14 at 10:29:53 This problem just showed up on my 2007 s40 ryca. I've never npticed this before, but my drum started rubbing when I roll the bike. I had odd tire wear on my first tire and just realized that the return spring was missing on the drum brake arm. I am taking the wheel off and cleaning the drum out and putting everything bacl together. Now I just have to wait for the ryca brake pedal stop. Hopefully this fixes everything. |
