Some thoughts -
1. I have an easy half dozen vanagon master cylinder reservoirs around, they
seem to last forever anyway, not worried about running out of those.

2. find a german car (  vw-audi ) similar res in a jnnkyard and experiment
on it.

3. a brake part is not normally something you want to do unorthadox repairs
to, though one might notice the brake fluid dribbling onto the floor or ones
feet, you'd think.

4. You could adapt a remote reservoir to your son's audi brake master
cylinder if you had to.

Subject: Linear or Cross-linked plastic in Brake Fluid Reservoir?

Pretty sure the plastic in the various VAG brake fluid and coolant
resivoirs is polyethylene, but was curious to know if anyone could
tell me if the poly is linear(ie weldable if cracked) or cross-lined
(pretty much not weldable).

son has a cracked at the stem resivoir on his 83 Audi CGT at the
nipple and is having a hard time finding a replacement.  I think this
info would be useful for Vanagon owners as well as plastic parts
begin to get scarce.
