Brake Pad Replacement.......

The question to ask did you replace the caliper as a complete unit from the mounting bracket bolts . If so then the caliper may not be sliding on the two bolts that position it on the mount bracket. If this is not allowed to slide free (rusted up) then after you apply the brakes the caliper will be pulled into position but when the brakes are released the caliper cannot centralise and so one side of the pad is held on the disc rotor.. It is a matter or taking out the long bolts ,one at a time, and cleaning and lubricating the pins so that the caliper is free to move.

Brake Pads Removal & Installation Front

To Remove:

1. Drain brake fluid to ½ full level in reservoir.
2. Remove the front wheels.
   
   
3. Remove the front brake caliper assembly.
4. Remove the 2 anti-squeal shims from each of the 2 brake pads.
5. Remove the wear indicator from each of the 2 brake pads.

To Install:
NOTE: When replacing worn pads, the anti-squeal shims must be replaced together with the pads.

1. Using a large C clamp or equivalent press piston into the caliper.
2. Apply disc brake grease to the inside of each anti-squeal shim.
3. Install the anti-squeal shims on each pad.
4. Install the pad wear indicator clip to the pads.
5. Install the pads with the pad wear indicator plate facing upward.
6. Install the brake caliper with the 2 mounting bolts. Torque the bolts 25 ft-lb (34 Nm).
7. Install the front wheels.
8. Fill the master cylinder with new clean brake fluid.
9. Pump the brake pedal several times to seat the brake pads.

The rear caliper cradle bolts are 18mm. A 19 may round the bolts off a bit.As far as them wearing unevenly we see this alot on the dual piston calipers.This may be due to rust underneath where the pads sit on the cradle. On the caliper cradle you will see some silver tin caliper hardware where the pads sit remove these and check for rust that may have built up benath these and clean if necessary. Once those are clean apply a thin coat of caliper lube then reinstall the caliper hardware. Make sure to also lubricate the hardware with lube before reinstalling your pads.Last but not least apply lubricant to the caliper guide pins.This will reduce that uneven wear you were referring to.
