Brake lock up - ZR-1 Net Registry Forums

Jim Nolan · 07-14-2014

If the check valve on the power booster sticks and doesn't release pressure will the brakes lock up. The Z was sitting for about 2 months and I took it out for a ride and one of the brakings the brakes stayed applied, the brake pedal was full up, hard as a rock, with no give to it. After the car was shut off for about 10 minutes then started back up all was normal. This happened about 5 years ago once and never again until yesterday.

The service manual does not give instructions for replacing. Is it just prying the old one out and lube and install the new.

Also no MPH reading and FX3 codes 23
