If not do not be distracted..

Your basic shoe movement will be the root cause.


Iíve stripped the one side that was rubbing and cannot for the life of me figure out what it is, I cleaned it, properly refitted and turnt the wheel whilst on the jacks itís moving but not very freely, Iím absolutely stumped on what to do

I had a mate who pushed the brake pedal for me(not all the way) only the front piston was moving is that meant to? The back one does move but only slowly and a bit jolty

Feeling like it could be something a bit more serious maybe cables? But even then I had checked them and they seemed OK

Re: Brake Drum and Shoes need replacing?

Sounds like the wheel cylinder is sticking..
Hence the dragging.

You can carefully remove drum and operate the brakes..

Handbrake on .off

Then foot brake on.off

Yeah I thought it didnít seem right, the leading brake piston doesnít move out but not sure if that would help would it?

Hereís a pic of the setup

So.. which system induces drag?

Handbrake is simplest.. so you can modulate forces.. for real.time comparisons.

1 thought.. are they definitely correct shoes.. 2 width options.. possibly diameter changes too.?

A sticky cylinder .. MIGHT . Stay out too long..

Con entionally the springs should overpower its resistance easily.. you should be able to see this

Well I stripped it all down, cleaned everything again I adjusted the self adjuster right in this time so there was no thread showing, put it all back together as before. There was a little dragging on the wheel so I initially thought I hadnít sorted it.

I hadnít driven it that day but the next morning I didnít hear any screeching or squealing from the wheels, they do get hot after a drive but not as hot as before, are the drums supposed to get hot? The handbrake is still high but I donít want to adjust anything just in case I mess anything up and it goes back to how it was before. Iím sure everything I fitted new was the same even springs etc as compared them to the original pieces

Re: Brake Drum and Shoes need replacing?

Brakes : friction

So SOME heat is to be expected.


Sounds like youve made progress.. and the self.adjusters 'might' reduce handbrake travel in time...through use

Keep us informed

Charlie

Sorry for late response keep having to make an account because having issues with logging in!😡

I hope Iím getting somewhere with it, Iíve noticed when I pull up the ashtray and the cables are being pulled at different lengths?
The passenger side is the one I was initially having trouble with but is now ok but the cable pulls up really high compared to the other side? Could this be down to what I done Friday? The car does hold on about 10-12 clicks when Iím on a hill which high lol

Re: Brake Drum and Shoes need replacing?

Sticking/stiff/siezed wheel cylinder piston means that piston will not "retract" ( pushed back into cylinder via shoe return springs ) so that shoe still "brake on".

Sticking/stiff/seized hand brake cable means that system will not allow shoes to return via springs to "off" state.

New shoes in worn drum, can cause "squeeks" sometimes as new shoes have a sharp edges that rub on a worn drum edges. So chamfer the friction lining of the shoes edges slightly.

Worn drums can be a real problem to remove sometime due to the wear, with the shoes having a central "valley", this part of the drum does not wear so stopping the drum from coming off. ALWAYS unadjust the shoes and handbrake cable BEFORE trying to remove the drums.

Also the outer edge of the drum can corroded leaving a raised corrosion edge making the drum difficult to remove sometimes.

Also shoes sit on back plate " flat raised area" which should be lubed with proper grease, using the "BARE MINIMUM" of grease., else they can squeek when the brakes are applied on, via pedal and/or handbrake.

If it moves it needs lubing.

Stiff wheel cylinder piston means new wheel cylinder with all its removing/fitting problems.

Penetrent penitrant penetrant over a few days on the union before trying to undo. Union may well be siezed/corroded into cylinder and pipe may well be seized/corroded into union, so be warned.

If halfrauds did do a BFC then the bleed nipple will have been undone.

looking at the picture the back plate could do with a de dust ( dust can also cause squeeks ) and a paint whilst you are there.

Personally i would fit the u shaped spring clips the right way up, but they are "locked" in place via the pins head and clip recess.

On finishing fitting and drum on etc., the brake shoes should be "centralised" via foot brake and adjusted, then re centralised and re adjusted if neccessary before handbrake cable is adjusted. After that, the self adjusting mechanism should cope as long as it it free and lubed.

Hope this helps and ALWAYS have a mask on.

I always used to remark that " if the brake dust does not kill you the brake cleaner will".

Re: Brake Drum and Shoes need replacing?

Thanks for that detailed description, I had it sorted but never had the chance to update, one of the handbrake cables was in a bad shape and had to be replaced, alll seems to be good now with the brakes etc, the handbrake is a little high still but Iím happy that it holds the car well now. Thanks all for your help

Re: Brake Drum and Shoes need replacing?

Good to hear you found the problem was the partially seized cable.

How many clicks on handbrake now?

Re: Brake Drum and Shoes need replacing?

My younger mj is due its MOT.. the brakes seem ok.. but range of travel seemed high

Counted the clicks today: four...
Travel did seem mildly reduced

but in your case of 8 that does sound excessive.

Try pressing hard on brake pedal before employing the handbrake..
The self.adjusters should do their job..

Charlie

I see, it will be something I will definitely look in to, car has cost me a fortune the past couple months :/

Itís been like it for a few weeks now shouldnít they have adjusted by now?
