I've recently fitted new rear shoes on my '88 Mini (owned for 6 months). I've followed guidance from several on-line vidoes and Haynes manual for adjusting the adjuster nuts and handbrake cable. Seemed fine for a few hundred miles. Then starting getting trouble holding car on uphill standing pull-aways. Made a second adjustment at the adjusters both sides and was ok again for a short while. Now its once again failing to hold car on uphills with as much force as I can get from the handbrake.
Is this just an indication of shoes bedding in and I need to keep adjusting or something else wrong? I've already fit new wheel cylinders (one was weeping fluid when I got the car). So should not be fluid contamination. The brake cable seemed to be near max tension on the adjuster already. Do these tend to stretch and need replacing?
Are there better shoe compounds I should consider (these were supplied by a local brit car specialist and didn't look like a familiar brand (Mintex, etc.).
