Brake Discs and Pads Rear plus Handbrake

Post by john23 » Sat Mar 20, 2010 11:24 pm

There is a Fact Sheet in Members Area about Handbrake adjustment. This says that the handbrake operates brake shoe "cunningly concealed within the rear Discs"
Confusion reigns!
My rear discs need replacing but I before I start the job I would like to know how the above handbrake operates on the discs
Anybody tackled this job ? Any guidance appreciated, thanks.

Rear brakes have discs & shoes operated hydraulically by the footbrake for normal braking & also a drum with the shoes inside it operated by a cable from the handbrake. So the brake disc is a drum is a disc :wink:
There is also a factsheet on changing brakepads etc that describes it all - http://www.igmaynard.co.uk/bongo/member ... kepads.pdf dead easy :wink:

changed mine a few weeks ago

you need it jacked up and the handbrake of....so chock the other wheels

took a couple of taps with a hammer and disk came loose

but a really simple job

took longer to jack and remove wheeels than to swap drums

they dont evan have a screw holding them

use a copper grease to stop them rusting to the hub

Thanks for the advice about the rear discs/drums, very helpful. Correct me if Im wrong but I guess the brake SHOES for the handbrake (not the pads) probably never wear out because the handbrake is only a static action as it never really acts on a rotating wheel (unless you do multiple handbrake turns!)

Exactly, unless you leave the handbrake on while you're driving a lot :wink: No actual braking is done with the shoes, just the discs.

Its been said that drum linings are more likely to need replacement because they've debonded with age. Wear shouldn't be an issue.

Prices don't seem to be as bad as they were if ebay ads can be believed.

Drum shoes have adjusters just like on the old drum brake cars. You have to line up a hole in the drum with the adjustment screw, do the screw up until the brake binds, then back in off a notch or two (can't remember exact amount but its in the workshop manual). Once you've done that, I would slacken the cable near the handbarake lever then get under the car and tighten the two branches of the handbrake cable from there (easy to see what to do once on ramps or axle stands) to get the handbrake lever close to correct. You then have plenty of adjustment you can use at the handbrake lever end for some time into the future if you need to adjust again. But adjusting the drum linings first is crucial to good brake performance I found, as without good geometry there, everything else is having to work too hard I suspect. You should only have to do it once every 15 years or so. My handbrake was rubbish before I did this, excellent since I did. Also, use it at traffic lights etc. as I suspect it likes regular use :lol:
