Residual pressure valve? (wilwood 260-3279)

Post by bmw2002e3 » Mon Jan 21st, 2013 12:06

I'm rebuilding my brakes from top to bottom, and from what I can tell the master cylinder on our '49s doesn't leave a little pressure in the line.
More modern cars with rear drums have a little pressure to keep the shoes nice and close to the drums.

Checking out wilwood's page http://wilwood.com/MasterCylinders/Mast ... alves.aspx

They have 10lb residual pressure valves which I could plumb into the lines. Thought is though, With a system designed
without them, am I just being fussy and asking for trouble by adding them?

Built in. Master cyl. stock parts has all you need!
Best to ya, read repair manuel on adjustments carefully on shoe adjustment/brake pedal to master cyl. rod adjustment. All should be well!
