I have had a very slight brake pedal pulsing when braking at high speeds for the last few years but it is becoming more noticeable now and I want to get rid of the pulsing. Original front rotors and replacement ThermoQuiet pads, truck is now at 215k kms / 130k mi. Truck has rear drums and applying the parking brake generates no pulsing. I am very easy on my brakes and the truck has been seldom braked hard, except for the few times I have been cut off in traffic. There has never been any sustained hard braking. I am the only one driving the truck. I have driven in a congested city for fifteen years and still have original brake shoes on one side at the rear (other side shoes had to be replaced after an axle oil leak)
This weekend I am going to check for rotor runout and the thickness of the rotor. Assuming those are still in specs, likely cause of the pulsing will be pad deposits. Any way of removing the deposits? I am considering
1) aggressive (knotted) wire brush on an angle grinder
2) brake rotor hone
Thoughts?
