Brake Caliper Seals

Unread post by bobthebuilder » Mon Mar 11, 2019 6:57 pm

My baby sprung a leak.

The piston inside the brake caliper is leaking. I removed the caliper and the piston and need to replace the o-ring.

I used to get parts like this from Placo, but since they closed up shop last year, I'm stuck.

To further complicate matters, the caliper came off a homebuilt aircraft, so I have no idea what caliper it is. It looks like a Cleveland 30-6, but the seal size is different.

I called East Rand seals, but they can only provide a metric seal, which I'm sure it's not. My feeling is that it should be in the region of 1/8 thick, with an ID of 1.5"

Can anyone help to identify the caliper, and refer me to an agent who can provide the seal.

It looks pretty rough now, so I plan to mask, bead blast, and give it some fresh paint. It would be a good time to rebuild the other one too at this time.

Bob, I take it you have come right in the meantime ? The other option is to have the caliper sleeved with a stainless insert, to a metric size slightly smaller, and have the piston cut down in a lathe to fit. Then just do the other side brake as well and , you have metric seals in future :D
