Rear brake

Postby glasshead » Wed Jul 20, 2011 1:50 pm



Here I am again. My rear brake pedal stays down when I step on it and locks the caliper. I wasn't aware of that until I put new pads on and bleed the system real good (used vacuum pump). The brakes were squeeking and grabbing when I pulled away from a stop. I thought it might be that the pads were worn down so far that the calipers were over extended. When I replaced the pads, the old ones weren't as worn as I thought (didn't really need replacing). After I bleed the brakes I pumped the pedal by hand to get fluid back in the line and that is when I noticed that I could lift the brake pedal back up by hand and the wheel turned freely. I thought this might be normal, that when the back wheel started moving it would somehow make the pedal come back up. Up on the stand and wheel spinning in 1st, no such luck. :cry:
Is it time to clean the calipers or master or both? :?:

I had a similar problem on my 79. It is tricky but you can take of the pedal while on the stand. It has a cotter pin and washer holding it on. I had to drive it off. I cleaned everything, emery clothed the peg and inside the pedal, greased it up and it slide on easly. about a 1/2hr job.

As mentioned, your problem is not with the calipers.. It is the pivoting bolt for the rear brake pedal that has seized up (Rust and gunk).
Try removing the pedal from the bike, clean the pivot, add grease and put the pedal back on, normal service should be resumed..

Thanx. Glad I asked before taking on the rear brake re-build. I did the front brakes, master and calipers, last summer.

I just finished cleaning and greasing the rear brake pedal. It was a real pain getting to the cotter pin, but a long metal rod with an angle cut on the end helped. I didn't even have to take it all the way off. Distonnected the clutch cable to get it out of the way, disconnect the brake light spring and disconnect the other cable connected to the back of the peddal. (Not sure what it does). Then I only had to slide the peddal off enough to get it off the fat part of the shaft. Cleaned that up and packed a bunch of grease in it and it moves down and up like silk. You guys are good as gold. :D :D :D

Thanx AGAIN

'Impossible' is just a level of difficulty! The only stupid question is the one you didn't ask first!
