I had a brake master give out on me. Seals leaked, brake fluid everywhere. Cool.
So, per recommendations around here, as my S5 had its booster bypassed long ago, I ordered and installed a Series II master. Bench bled. Installed. After what seemed like too little bleeding, I had solid pedal feel, like almost zero movement (odd for SII master in an S5). The wife called me in for dinner, so I went to roll Miss Moneypenny into her parking spot and she wouldn’t budge, all four wheels locked. Long story short, the brakes aren’t releasing.
Here are some of the things I’ve done and their results:
1. Removed the drums - return springs are in place and fairly new.
2. Removed the master to bench - sprays fluid, springs back.
3. Reinstalled the master - locks up (albeit less so, as I didn’t rebleed)
4. Inspected the hard line to the pressure switch -no kinks.
5. Removed the hard line - sprays fluid, master springs back.
6. Hooked the hard line back up (master on but not installed, worked by hand) - fronts locked, rears not.
7. Reinstalled everything - four-wheel lock
8. Readjusted rears, rebled everything - everything locks except right rear.
9. Readjusted left rear - fronts lock.
Usual suspects:
1. Rod length - irrelevant, as it’s doing the same behavior on or off the firewall.
2. Collapsed brake hose - those were replaced with stainless braided five or so years ago.
3. Kinked hardline - nope.
4. A vengeful God punishing me for past indiscretions - repented, no change.
Any ideas?
