Wheel brake bit, not Edson. Help!

Don't know what type of pedestal I have. Boat was built in England about 1985.

The picture is of the wheel brake housing. The knob drives the screw in which dribble the grey bit against a collar to lock the wheel. The grey bit is some kind of plastic cylinder, maybe PVC or HDPE?

The pencil is wedged under the grey bit.

The grey bit is worn out, too short, shot. I need another.

Any clues?

Good luck but it's probably not high density plastic, that's very slippery. You can get brake shoe material in most US towns. They still reline brake shoes even in 2015.

It is most definitely NOT any kind of brake shoe material I have ever seen.

If it's not obvious from the photo it is formed into a cylinder, the head is a bit bent over. It measures 0.41" diameter.

I agree that plastic is very slippery and, despite what I would expect, this is exactly what it appears to be.

Odd? Yes, but it is what it is.

I doubt you will find original parts. Try alternate materials such as phenolic resin impregnated fabric. Try McMaster Carr for this and other brake lining materials McMaster-Carr In some cases, cast iron makes a good brake pad.

Re: Wheel brake bit, not Edson. Help!

I spent some time last night looking for Whitlock parts. Found winch servicing.com, which seems to be the remnants of the operation. But no solid info. What drawings were posted where of a different unit. I may try writing to them ans see what they say.

I don't see ANY pedestals with a similar brake. This brake does not go into the pedestal as many. It is mounted on the wheel shaft as it comes out of the pedestal.

I have used exhaust hose cut to side as break pads.

The material seems to be 10mm in diameter.

It seems urethane has a pretty high coefficient of friction.

So I ordered a bit of that, we will see.

After that my next go will be a bit of 3/8" aluminum.

An experiment.

Re: Wheel brake bit, not Edson. Help!

Having spent a fair bit of effort trying to find what this was, with no luck I looked up coefficient of friction for some various combinations. The best candidates seemed to be urethane and aluminum.

I got some 10mm urethane round bar. But that was very soft and pliable. I have not tried it but I am very dubious it would work.

I got some 3/8" round aluminum bar from Lowes. That seems to work OK. more of a drag than a lock, and it releases pretty quickly. But that may change as it wears in and takes the contour of the bearing surface. Looks like it is about as good as it gets for the moment.
