Hello, I am experiencing some brake oddities that I'd like some help with. Nobody seems to have my exact combination of issues so here goes:
My 60 had a pulsing brake pedal and under hard braking, the right rear would lock up. The vehicle also pulled to the right. I noticed the front right rotor had been eaten away on the inner face by a pad that presumably wore out and grinded away the surface (pad in there was fine). I assume this rotor was warped.
Fast forward 2 weeks ago, I changed both front rotors, new advics pads, hardware, and new front hoses.
Pedal shimmy went away, but vehicle still pulled to the right. Right rear drum also still locked up under heavy braking.
4 days ago, i replaced the rest of the brake hoses (now all new), master cylinder (advics brand), and rear wheel cylinders, drums shoes, and hardware. Cleaned self adjusters, verified function.
Vehicle still pulls right, and the right rear drum still locks up first. Also, while I was on the highway, I experienced a serious pedal pulsation while braking, felt through the steering wheel. Strangely though, this was only observed when braking 2-3 times before it went away.... weird. Felt just like a warped rotor but now it's gone.
Brakes have been bled a few times at this point.
One thing to note is that when i was bench bleeding the master (while installed on vehicle with some hoses routed to reservoir) the line closest to the firewall would push fluid, but the line near the front of the vehicle would not push any fluid until halfway down the brake pedal's travel. So fluid from one for first half of stroke, then fluid from both. No matter how long I bench bled, it was always like this. Immediately after installing the master, I went for a test drove and everything was exactly the same as before I changed the master.
