i have a 1997 honda civic and my driver side caliper is getting stuck, i have replaced it with a new one as well as a new master cylinder and still it gets stuck. when i remove the hose that goes from the intake manifol to the brake booster the brake releases and the car roll freely, any other thoughts to what it could be?

 

Sounds like you may need a new booster, but check your flex line to the caliper as well. Odd for the booster to be locking up only ONE of the calipers.

 

yup its only locking the driver side, it was replaced and lubed all the moving parts like sliders, hose is good not braking or falling apart, the mystery here is its only looking the driver side and once the booster line is removed the caliper releases instantly

 

Also look for a check valve on your booster. Normally they don't fail, but anything is possible. Cheap fix if that ends up being your problem, or part of your problem.
