Where are the possible points in a brake power booster that could have a leak?
My Mazda 3 2008 model was noticed to have an air leak when you press the
brake pedal heavily or suddenly. The mechanic informed me that it is because
of a leak in the brake power booster thereby advised us to have the brake
booster replaced with a new one and it costs so high.
That is something that you can not fix without replacing the brake booster.
