Title: Changing rear disc brake
Post by rpgpgmr on 08/01/08 at 08:06:10

Having trouble finding any discussions on replacing the rear disc brake ... is it a bad idea to attempt that oursevles or something? I'm getting ready to put on the red EBCs in the front, but I think I can get away with just tightening the rear adjuster for the rear brake. However, if I were to need to replace the rear disc is that something I should leave to an expert? I hope not cause I like doing this stuff myself--and it's cheaper. 8-) I've found how-to's on here for just about everything (and done a lot of 'em), but don't see any on this subject.

My 07 has drum brakes in the rear. pretty sure I would not attempt to change those myself.

I have an '05 which is the same bike so I'm sure that mine's a drum too ... not very proficient at the proper name of these parts. I'm afraid I'd be getting into something I can't get myself out of if I try to do that myself ... especially since I couldn't find any place on here where anybody else has done it. If these guys haven't done it, then it's probaby not a good idea to try it!

All you do is pull the rear wheel off,and the the brakes come right out with the whole drum assembly.There is a manual online in the tech section.

I thought I was the only SOB that wants rear disk.

We all have rear drum brakes, tighten the nut to adjust the brakes.

To inspect/replace the braking media (aka shoes instead of pads) requires the removal of the rear wheel. When the brake material gets thin replace the shoes. You can have the shoes ground to match the drum or not. ;D

My guess is that it's never been discussed because nobody has ever had to do it. Those things should last three days longer than forever.

Look in the tech section, there was a write up on it in there which is what I used to replace my brake shoes.

I bought a pair of shoes 'cause they were squeeling an' I thought it might be worn out shoes. HA!! Buggers look unused.

There is about four times the surface area on the shoes as the front pads, and the fronts do 70% plus of the braking work. So shoes should last about ten times longer than the pads, or something well over 50,000 miles.

Thats right - and I got a bazillion miles left on mine judging by the wear indicator cast into the backing plate by the pivot arm. Reckon I will have gone through 100 pads for the front disc by the time the rear needs attention!

No idea why that post didn't come up in my search. A few months ago I read EVERY post in the Tech Section, but it was so much information that most of it has long left me. :) Once I started reading I remembered it ... vaguely. Since I'm only at 9800 miles I'm sure it just needs tightening a bit. Nice to know that there's a how-to out there for when I actually need to though. Thanks!

Just do not tighten the adjuster nut tight.If you can jack the back tire in the air(regular floor jack will work) tighten the nut a couple of turns(not complete turns)there is recess on the nut,every half turn it will sit against the pivot pin(you'll understand when you look at).Spin the wheel make sure it IS NOT dragging,and check your brake pedal it should move about an inch or so(+ or -) ;)

The adjusting nut has to be taken off and put back every time the rear tire is changed anyway. That's probably the only adjustment it will ever need.

Well when I first bought the bike, I had to tighten it up a bit to even make it useful. I was having to darn near stand on it before it would engage enough to slow me down. That was a year ago so I've just worn a little more of the pads and need to tighten it a little more.

Believe it or not I don't have a floor jack, but I'm gonna get one ASAP. Keep in mind I've only been a Do-It-Yourself'er for about 5 months. I just buy tools as I need them now.

Theres a line in the "Axle" the brake engagement arm tightens up on. There is a "Useful life of the brake" graph on the rear wheel that the line points at. If you can feel the brake pedal is not pushing the brake lining into contact with the drum, then you can tighten the adjuster nut to remove the freeplay in the pedal. Reach down & move the arm the brake cable pulls & see where the line points to, or, if your arm is long enough, push the pedal down & see where it points. Mine has 18,000 miles on it, Ive even cut a good %age of the brake shoe out, so it doesnt lock up so easily & still, it's not wearing at an alarming rate. Still squalls a bit,

Since I no longer have a disk brake in front because of the Girder front end not being wide enough to accept the disk, I have been using my back brake far more lately, I still haven't noticed much wear compared to the front.
