increased friction material thickness of new pads, It may be necessary to remove the master cylinder reservoir cover anddiaphragm and remove some fluid.

9 Smear the backs of the pads and the shank
of the pad pin lightly with copper-based
grease, making sure that none gets on the
front or sides of the pads.

10 Installation of the pads is the reverse of removal. Make sure the pad spring is correctly positioned in the caliper mouth and the pad plate is in place on the caliper bracket (seeillustration 3.2a andb). Insert the pads into the caliper so that the friction material faces the disc, making sure they locate correctly against the pad spring and pad plate, then push up on the pads to align the holes in the pads with the holes in the caliper. Slide the pad retaining pin into place (see Steps 1 and 2) making sure the pin passes through the hole in each pad.

11 On R and T models, tighten the pad

retaining pin to the torque setting specified at the beginning of this Chapter. Install the pad pin plug and tighten it to the specified torque.

12 On V, W, SW, X, SX, Y and SY models, insert the R-pin through the hole in the pad retaining pin.

13 Check the level of fluid in the master cylinder reservoir and top-up if necessary (see Daily (pre-ride) checks).

14 Operate the brake lever several times to bring the pads into contact with the disc. Check the operation of the brake before riding the motorcycle.

Warning: If the caliper indicates the need for an overhaul (usually due to leaking fluid or sticky operation), all old brake fluid

should be flushed from the system. Also, the dust created by the brake system may contain asbestos, which is harmful to your health. Never blow it out with compressed air and don't inhale any of it. An approved filtering mask should be worn when working on the brakes. Do not, under any circumstances, use petroleum-based solvents to clean brake parts. Use clean brake fluid, brake cleaner or denatured alcohol only.

Removal

1 If the caliper is just being displaced, the brake pads can be left in place and it is not necessary to disconnect the brake hose.

2 If the caliper is being overhauled, read through the entire procedure first and make sure that you have obtained all the new parts required, including some new DOT 4 brake fluid (see illustrations).

3Remove the brake pads (see Section 2). Note the alignment of the brake hose on the
