50 mph touch the brakes, periodically the abs prevents me from depressing the pedal. after the millisecond of panic immediately i release and tap again, again periodic symptom, extreme pulling to the right, sometimes to the left, another periodic symptom, in parking lots at very low speed, easing into a parking space, alot of resistance from the pedal, easing up on the pedal and reapplying pressure, sometimes the brick dont wanna stop at very low speed,and then it catches and front end plunge when the brakes grab, have changed the pads and grease those pins on the calipers, i have cleaned the abs sensors on the front i have a certified volvo mechanic and the 88 760 i guess is a rare bird, i love this car, and i will spend the money, i realize this is a shot in the dark, this problem has stumped us for 5 months now, weve tried the abs box on the firewal, its got a new master cylinder, new front pads cleaned the sensors on the front also cleaned the debris and brake dust from those gear looking things the sensors read on the front rotor thing, correct terminology, i want to take the brick on vacation this summer, the abs sensor on the rear transaxle is next, i am tired of hanging parts just for the hell of it, please ol volvo gods enlighten me
