Hi all new memeber ,
I have had a problem with my brakes which have been going on for 2.5 years and cannot get fixed .
Front right is binding so, wear this pad to metal in about 6000 miles (5-6months)(also seems that rear left seems to be a bit heavy on wear as well but not so bad). I have followed other advice in diffrent forums but have not fixed . This was replace caliper on right and have changed the hoses on the front . It seems ok for few hundred miles but then the wheel feels warm a lot hotter then other side . It doent pull and acceraltes in a straight line .
Passes the MOT all ok , not giving any cause of concerns apart form eating pads and discs .
Its just a standard brake system with abs .
The only thing left is the master cylinder or ABS unit . Which of these 2 would you try next as cannot continue replacing pads every 6 months
Im really stuffed on this problem.Any kind help would be a great benift
Cheers
Simon

For starters I don't know the workings of that car.
However, many cars have a dual circuit system where the front left, rear right are on one circuit and vise verse so your connection between wear right front and left rear could be valid.
The master cylinder has an arrangement of two pistons in line operating the two circuits.
When the brake is pressed the pistons pass and close holes which are connected to the reservoir. When the brake is released the holes are uncovered and fluid can return to the reservoir. If the rod between the pedal and the master cylinder is too long (some are adjustable)or something is preventing the pedal from coming fully back then the fluid cannot return to the reservoir leaving the system still pressurised and slightly applying the brakes. The tolerances could be that this is only affecting one circuit.
I have seen this where the carpet had ridden up the footwell and jammed the pedal.
Check that with the pedal up (don't pull on it yet) there is a little bit of end float in the rod to the master cylinder. You can then also see if the pedal will pull up any further.
The rod you are checking will be going into the servo. There is another rod from the servo to the master cylinder but it is not going to be as easy to check that one but again some designs are adjustable.
