Subject:Caliper Bleeder Screw: RF Typically Seize More Often?
From:neil n

Hi all.

Took my '88 Westy to a shop. Shortly after work done, felt a short
noticeable shudder braking at highway speeds. In checking the shops
work. (wheel fasteners, etc.), noticed the RF bleeder was untouched.
It won't turn, the other 3 do. Shop had flushed the brakes. Asked the
shop about this screw, they said they bled that wheel at a hose union
(but I can't see any wrench marks at any of those unions...... That's
another story)

Before taking van to shop, I sprayed penetrating fluid on bleeder
screws well in advance. Maybe I missed spraying the RF bleeder
but.....

Is the RF bleeder any more prone to seizing than the LF bleeder?
Strange question but I'm trying to determine if it's worth tackling
this part or just wait until I do both calipers, hoses etc.

I saw Alistairs page, and a few comments (thanks Scott) on getting a
stuck bleeder loose.

What I've done:

- applied penetrating fluid
- applied heat to caliper body (butane torch, nothing too hot)
- tapped on the end of the bleeder with a small hammer
- picked rust/dirt away from threads at caliper body

I plan on wrapping a small rag around the bleeder and soaking it with
penetrating fluid to keep it all "wet".

Any other tips to loosening the bleeder are welcome!

Neil.
