[DML] Re: Brake booster/Servo troubleshooting



Raise the car and make sure when you step on the brake pedal each
wheel is held tight by the brake system. You could have a caliper that
is frozen or maybe a bad master cylinder or a hose. Assuming the brake
system stops each wheel try driving the car with the vacuum hose to
the brake booster removed and plugged off. If you do not notice any
difference with the booster connected or not then it is probably bad.
There is no diffinitive test except on a test bench. The brakes on a
Delorean are not great but they are good (at least when they are
working right). If you did not get all of your parts from one of the
Delorean vendors maybe it is possible you did not get the right parts.
The wrong master cylinder can have a large effect. As can the brake
pads. Look inside the vacuum hose and see if it shows any sign of
wetness. If it does you can assume the booster is bad and you are
sucking brake fluid through it. A final possibilty is a
way-out-of-adjustment pushrod. This is not easy to diagnose. It is the
small rod that comes out of the booster and pushes on the master
cylinder. It has an adjustable end to make it longer or shorter. If it
is too long the brakes won't release (compensate properly), too short
and you have to move the brake pedal too much to get the brakes to work.
