Re: Seizing brakes

I suspect the contaminated shoes will be grabbing and if not fixed could end up fully locked. Clios are renowned for this problem.

The drums and all aspects of the inner drum, springs will need to be dismantled and thoroughly cleaned otherwise when new shoes are fitted the problem is likely to come back.

Ideally the drums should be renewed and only by gently heating them are you likely to drive all the brake fluid contamination out of them as the metal is porous. Wipe the drims out with a suitable brake cleaner and then gently heat the drums around their circumference (a small blow-lamp or hot-air gun does the job nicely) and you will actiually see the comtamination being forced to the surface. Wipe the drums again and then emery the brake surface and especially the wear edges.

Firts release the handbrake ajuster to its full extent.
Once all is thoroughly cleaned - assemble correctly - and adjust the adjusters by hand in small increments until the brake drum just eases into place. Then depress the foot brake and operate the handbrake a few times and then check again and see if you can get any furher adjustment. Once happy with the foot brake adjust the handbrake up until both wheels lock - then release the adjustment until both wheels are free with just a hint of the shoes touching the drums as they are rotated.
