problem with brakes as well

[LordDurock]

hey guys i have trouble with me brakes a well.
the problem is the rear passger side wheel locks up for the first few brakeing times then it kinda goes away (meaning i can fell the rear pass pull kinda hard while braking after that but it doesnt lock up)

thew weird thing is the frist time is locks up the pedal acts like it hit a brick wall half way down as you pump the brakes (what i do to get past the locking up) the pedal get softer and softer tell the it fell normal and the rear doesnt lock up. it seem to be a problem that a sencor can pick up beucase it trips the brake dummy light

anyways thought it was a leaky wheel clinder but that not the case i checked.

any thoughts

This is a common problem with the A-bodys. Brakes out of adjustment is usually the culprit. Sometimes its just easier to replace the rear braking system with new drums, hardware, and shoes thou.
