I have a 2001 GMC 1500. Sometimes when applying brakes,my brakes pulses,all the way to the foor and doesn't want to stop me. No lights are on. And no code are coming up. Have new brakes.
Truck is in very good shape. Only 75000 miles. Could it be the master
cylinder? Only done this 5 times. But peddle go,s all the way to floor. In about
3 pulse.
