Brake question, no tassles.

[drew@scirocco.cs.uoguelph.ca (Drew MacPherson)]

Cathy, the o-rings aren't available from VW as separate parts.  having 
said that, if you can match up a replacement part (which will be 
challenging from the ring that has split, because it will also likely be 
stretched) you should be able to replace them.  Many auto parts stores 
sell o-ring kits that include common metric/imperial o-ring sizes, or they 
may sell individual rings.

I have a similar problem - one of my pressure regulators has been seeping 
brake fluid for some time - just enough to make the regulator damp, but 
not enough that the level of brake fluid has gone done significantly.  I 
hope to replace the offending regulator with a spare before the spring 
season starts.
