Have a 42 with 42 brakes. Car does not stop good. All new brakes 3oo miles ago. Removed one front drum and saw that the rear shoe was almost half worn down. Cylinder was working both sides. Besides going and re adjusting all wheels at both top and lower pivot points, what else should I try?

Hard to believe that the shoe would be that worn in 300 miles. Must have been dragging all the time. Were the drums turned when you did the brake job? Bonded or woven linings? When adjusting and when the wheel turns freely apply the brakes hard and then be sure the shoes are still free. Then drive the car forward and apply the brakes and then backward. For the front shoe to be worn that much I would think it would have been pulling to that side. There is only an adjustment at the top which is an eccentric cam. John

sounds like a bad truning of the drums,were they smooth when you installed them, also were did you buy the brake lining ? were they new or old stock ? were the drums dragging when you finished adjusting the brakes,? did the master cylinder have free play ??? so brakes were not dragging, did you smell anything , like brake lining's? BURNING? more info would be helpful, get back to us,thanks 37RAGTOPMAN

Two main possibilities: As said, the master cylinder may not have had at least one inch of free play to allow the fluid to return to the reservoir, allowing pressure to build up, or the holding valve in the master cylinder is stuck. That valve keeps a small bit of pressure in the system so you don't have to pump up the brakes each time you stop. Pull all drums and examine for excess wear. If all show wear, suspect the master cylinder. If just one front brake shows wear, it is likely that the inside of the brake hose on that side has collapsed and is not allowing the wheel cylinder to retract. If only the secondary (short) shoe is worn, but not the front (primary) shoe, it is likely that the piston is stuck in that cylinder. Just because it was recently replaced doesn't mean it is good. Be sure that the brake shoe return springs are in good condition. We always replace the springs on each brake job. Don't try to adjust the pivots until you find the problem. Most of the braking power is concentrated in the front end, so if one side isn't working, your brakes will be weak. I'd suspect the secondary shoe was trying to make up for lack of force from the front cylinder piston.
