Dragging Brake??

[Michael Williams]

Sorry about the way I worded it. No, both pads on the left caliper had worn down equally but much more so than the pads on the right caliper. The pads on the right caliper looked like they were hardly used. 
Huw had brought up a point of the lines being a dual diagonal brake circuit and the proportioning valve being involved. If that is the case then I should find similar symptoms on the right rear. Correct?

Hi Mike;

It's not clear from your post, but I assume on the left front caliper the
inner (piston side ) pad was worn more than the outer pad.
If this is the case, your problem is probably seized caliper guide pins.
