Removal

Note! Minimum thickness for replacing the brake pads = 2 mm.

Remove the retaining springs and locating pins for the brake pads.





Remove:

- the protective caps (1) from the two locating pins (2)
- the locating pins, use hex socket 7 mm.

- the brake pads.
Hang the brake caliper by a steel wire from the spring so as not to damage the brake hose.

Clean and check the brake caliper and dust cover




Clean and check the brake pad mating surfaces in the brake caliper and caliper holder.
Clean the sliding pins using a steel brush.

Note! If the dust boot is damaged dirt may have penetrated the cylinder. The brake caliper must be reconditioned. See Reconditioning rear brake calipers Reconditioning Rear Brake Calipers.

Check the brake disc




Check brake disc friction surfaces.
If the brake disc displays signs of out-of-true, check its lateral run out. See Brake disc rear, calibrating Brake Disc Rear, Calibrating.
Replace the brake disc if it displays signs of heavy wear, variable thickness or similar. To replace, see Brake disc rear, replacing, B5244T5, B5254T2 Brake Disc Rear, Replacing.
