are the rear brakes adjusted ? the rear brake pads good ? are the rear wheel cylinders leaking or sticking ? is the proportional valve working ? do you have really skinny tall tires on the front? does the car pull to one side or another when brakeing ? do you hear anything grinding front or rear while driveing ? do you hear anything grinding or rubbing while brakeing ? do you drive with your foot on the brake pedal ? are your wheel bearings good ?
1971 Plymouth 'Cuda 440-6 power brakes with stock front disc rear drum.
Both of my front brakes seem to be locking up. The car drives and stops fine. I can't feel the brakes drag and the car does not pull to one side or the other when I apply the brakes or when cruising.
I noticed a lot of brake dust on the front wheels, so I jacked the front end of my car up and both front wheels where really hard to spin by hand, like really hard. Both rear wheels are fine.
The parts that are new or freshly overhauled: power booster, master cylinder, both calipers, discs and pads.
At that point, I replaced the master cylinder with a different overhauled one. Same problem.
If I let the car set for a while, the pressure lets off and the wheel spin freely again until I drive the car.
