Re: Bedding-Down Parking Brake
How do I say this, and keep this page "G" rated?
In this case, "bedding down" or "bed-in" of brake shoe material and the iron drum is more akin to the exchange of bodily materials, and the driving out of inhibitions......
So.... Brakes don't work well when the mating surfaces are completely dissimilar. Brakes work best when a bit of pad material makes it's way into the porous surface of the iron, and a tiny bit of iron makes it into the pad. When they become one by the exchange of materials, they bind together for maximum friction. The second aspect is that the heat drives out some of the adhesive resins that hold the pad fibers together, increasing the effective surface area.
As you use your parking brake in a stationary mode 100% of the time, you rarely do the above two actions. If you drive relatively slowly and lightly push on the parking brake, perhaps you could get them to slow the car without locking up the rears. Repeat it a few times in a safe place in case you overpush and lock up the rears. That would probably do the job.
