I have replaced the following without any effect: L&R side flexible brake lines (new), R side caliper (rebuilt), caliper bracket and slide pins (new), parking brake return spring (new), L&R rotors and pads, as well as the load sensing proportioning valve (salvaged). All with no change.
When jacked up and the road wheel removed, the rotor hub may be turned by hand with slight drag (deemed 'normal'), however if foot brake is depressed
the brakes are 'locked' (deemed 'excessive') until caliper is wriggled by hand.
What can account for this, how do I debug it and what is the cure? The car will soon be used for two new drivers about to enter the driving world so safety/reliability is a primary concern, but cost is also a consideration.
o-Brake fluid flush/replace?
o-Master Cylinder test procedures?
o-ABS test procedures?
o-TSB or known issues?
have the same problem?
