Brake Shoes

**101RRS** · 9th March 2008, 07:28 PM

For the past few weeks I have been trying to get the brakes in my 101 working. They are basically the same as LWB 6 cylinder Series 3s and Stage 1s. Having spent mega $$ on brake bits and pieces, the main issue has been bleeding the rear brakes - I couldn't - by pumping from the master cylinder or sucking using a vacuum bleeder.

I started from the master cylinder and worked through the system - should have worked the other way around. Anyway fluid was getting to the wheel cylinder but not coming out the bleed screw.

I removed the wheel cylinder and found that the brake shoes had pushed in the pistons in that far that the hole that lets the fluid into the cylinder was blocked.

My trailing shoe has a large pimple on it (see pic) that the wheel cylinder actuates - is this normal. The leading shoe which is less clear does not have this. The picture is the top of the shoes - the gap is where the wheel cylinder goes.

Ultimately this will not be an issue because when the the brakes are adjusted up the wheel cylinder will be clear of the hole - but if I had fitted new shoes (mine are about half worn - but OK) I would expect the hole in the cylinder would be blocked and the brakes will not work.

The other rear brake is exactly the same and has the same problem - clearly something is not right.

Any ideas.

Thanks

Hi Gary
Did you wind the shoes up to as tight as they go before bleeding(with the snail cam adjusters)???
It helps no end,the fluid is then only moving thru the system only,not pushing pads out.

I agree with LandyAndy but it might be worth checking that the shoes are around the right way and they are centralising correctly, if you have a problem with the return spring catching then the pistons will pull in enough to block the holes in the cylinder.

Thanks for the comments - normally I would wind them out as you indicated but this time I read the service manual first - it says "slacken off the brake shoe adjusters on each wheel to minimise wheel cylinder volume". I am damned if I do and I am damned if I don't - never read a VCR programming guide in my life - read a service manual and get a bum steer.

I have double checked the brake shoes and they are the right way around - dunno about the spring catching but I don't think so.

That pimple on the trailing shoe is far more pronounced than the leading shoe so I am not sure it is supposed to be like that. Certainly my series 1 shoes do not have it. I was wondering if it has been added by a previous owner as a bush fix to an issue - it just does not look right.

Cheers

for the initial bleed up (which is a gravity bleed) you back the shoes rightup, assuming that this minimises the space correctly then both ports should be open and as soon as you get brake fluid turning up at the bleed nipple, lock it off, check that the resivior isnt low then wind the adjusters out.

The series rovers were alway a PITA to get to bleed up properly and I cant imagine an fc101 being any more fun.

if you can get your hands on one try a pressure bleeder that clips onto the master cylinder and pumps brake fliud at about 15psi. I prefer the vac bleed method but if that aint playing then its time for the big guns.

as for the nipple on the spine of the shoe most shoes have them...

Ive previously done up a thread on checking your backing plates and brakes theres some pics on it that might just help you out.

Best of luck with it.

Thanks Dave - that is really helpful.
