one rear brake getting too hot

MilesnMiles · Post by **MilesnMiles** » Tue Aug 27, 13 5:25 pm

smelt 'hot' today so checked rear brakes. Drivers side too hot to touch, passenger side luke warm.
removed the brake drum and loosened the adjustor right off although the brake drum wasn't catching on the shoes much.

All hardware is new. Can anyone see anything wrong in the enclosed pics?

If the wheel cylinder isn't new I'd suggest the piston inside may be sticking, Miles.

Park brake lever or cable isn't sticking either, is it?

Phill everything is new. The parking brake system is new in every respect. I was wondering of somehow the adjuster could somehow be tightening up, but the system is designed to not allow that.
Even the brake drums are new so I have discounted warpage.

That said, I could swap the two rear drums just in case. Don't want this to stop me attending the HRDs

I found this thread. Guy had identical problem

Does the parking brake operate mostly on one side?

It is very strong, guy at the MOT was shocked by how it pulled up. Wondering if its over adjusted somehow?

Are you sure the shoes are in right? You should have a leading and trailing edge on each shoe, if you fit them wrong they will drag and create heat build up.

Hmm, I didn't do the install. Can you describe or have a pic of how they should look by any chance?

Shoes normally have a long and short bit off each end with no braking material on. The shoe nearest the front of the car should have the long bit up top

Looking at the close up shot of the adjuster I'd say that maybe it is not seated fully, judging by the adjuster wheel witness marks on the adjuster lever itself.

Difficult to say without seeing it in 3D!

Found some images, although the poster is also having issues with his adjuster!

Is there a spring missing?

you know, the little one that fits in at the bottom by the adjuster. The one that cause's all the grased knuckles when you try and stretch it, think it should go in the small hole to the left of the adjuster seen in picture 2.

Having said that, it also looks like the adjuster isn't sitting right on the right hand side?

Thanks all. no springs missing that I can see following the links to other correct installations.

Phil, not sure what you mean by the 'witness marks' being wrong. Can you be a little more specific, please.

The adjusters have been manually backed off by me. The star piece and lever are acting correctly. I had to gently prise the lever away from the star piece some could manually wind in the adjuster with the drum off.

The car will roll back and forward easily, the drum came off easy, but it is getting hot and still can't figure it out.

If the drum was stuck/tight I suspect the culprit would be more obvious.

When looking at it you have 2 shoes left and right

Between them you have the adjuster

The left shoes sits between a fork of the adjuster

The right side of the adjuster is not seated correctly on the right shoes.

On the adjuster you have a spiky wheel that spins around and clicks on that bracket thing. The dent in the bracket thing from the last 50 years of clicks is in a diffrent place

I know this seems dumb

, but staring at the pic in Phil's thread...

..I can barely see the difference.

I think tonight i'll take of the passenger side and see how it looks in comparison.
Nearly all the hardware is new (not the adjutor) including the bracket thingy which the star wheel works on.

I guess misasembly has to be the obvious culprit.
