Hey guys i was driving through the back roads when a dog ran out and i slammed the brakes on. i guess i have abs cause it didnt just skid it gradually slowed down from about 55. i was cruising around later and noticed my jeep to be very sluggish got down and looked and my disk bakes are locked up. so i let it sit for a while turn it back on and the pedal is spongy and needed to be pumped like when my clutch master cylinder went out. Do you think its the brake master cylinder? The guy at my local auto parts store mentioned the proportining valve.
What do you guys think?
