Hi everyone,

Just a quick one, will my rear drums on my car have/need a spacer when I come to change one of them this week? Just so I know before I order.

You'll need spaced drums, or separate spacers.

Why are you changing one of them?

[rawky]

The brake on one side turns 3/4 of a turn, then binds, then moves freely again. I suspect the drum is warped?

Bump

Am I right in my diagnosis?

Not necessarily (although possible of course) - could be wheel bearing problem, or a 'rusty patch' on the drum rubbing face. I would clean and swap them side to side and see what happens first.

When changing you must change both at the same time, also some people reccomend changing shoes aswell.
Same thing with discs and pads

Hmm ok, I'll do that. I haven't heard anything from the bearing, but I'll take the drum out and take a look.

Ah I hadn't considered that, cheers

I have since replaced the pads and drums, and also new handbrake cables. However this still persists, at slow speeds the rear right drum groans rhythmically, as if it is binding every three quarters of a turn...

Could the stud axle be bent or something?!

YOU CHANGE BRAKES IN PAIRS!

YOU NEVER EVER THINK OF REPLACING JUST ONE SIDE!

[rawky]

Take your headphones out, you're shouting

I haven't, I replaced both sides. Any ideas anyone?

When you say it is binding do you mean with the wheel clear of the ground it requires some force to rotate the wheel or is it just gently rubbing/catching? If the latter back off the adjuster a couple of clicks and try again. When fully assembled new shoes and drums will always have a high spot.

I tend to adjust the brakes so this high spot just becomes evident by the gentle rubbing sound. Have you run the vehicle far since changing the parts?

You didn't mention the results of looking at the bearing, whilst on axle stands (Safety) with the wheel fitted can you grasp the wheel at 3 & 9 o'clock and try to rock the wheel, is there any play? Try the same at 12 & 6 o'clock.

Hope This Helps,

Barry

It would seem it has this high point you're talking about, but it only happens on one side? It takes a good amount of force to get it past this high point!

I haven't run it very far no, but this new symptom of the wheel clicking at speed concerns me, any ideas?

It's just passed MOT with no play in the wheel bearings!

Cheers

Amazing car, it seems to have fixed itself. Maybe the high spot has just worn down?

The ticking noise was caused by slack in the handbrake mechanism allowing the linings to hit the backplate as I drove along. Really loud clack clack clack noise has now gone!

[Ben1400]

Hi,

Yes it could have worn the high spot down, it doesn't take many miles.

Slack in the handbrake cables/mechanism should not cause your brake shoes to rattle against the back plate. If it was me I would have the brakes apart to check they have not been reassembled incorrectly/have springs missing or broke.

I assume you have tightened the handbrake cable up and the noise has stopped happening now. I believe that this is only masking the real problem. Compare the shoe/spring/handbrake lever arrangement with the manual diagrams. This sounds very dodgy to me!!!!

If you are unsure at all, take it to a garage/quick fit sort of place. Brake failure is no fun!

Regards,

Barry
