CALIPER CLEAN­ING TIPS

Motorcycle News (UK) - - Garage -

1. Work on one caliper at a time. Push out the brake pis­tons by re­mov­ing the pads and pump­ing the brake lever, hold­ing back the looser pis­tons with your fin­gers. Only push the pis­tons out so you can see the ‘tide line’ of brake dust, don’t go any fur­ther or the pis­tons may come out of the bores al­to­gether. 2. Put on some ni­trile gloves and us­ing brake cleaner (and only brake cleaner) spray the pis­tons well and ag­i­tate with an old tooth­brush. More stub­born de­bris can be re­moved with light use of a green scourer. 3. With all brake dust re­moved check the con­di­tion of the pis­tons for any se­ri­ous pit­ting.

4. With a small brush thinly smear on red rub­ber grease around each pis­ton. You can buy red rub­ber grease in small sa­chets from your lo­cal car ac­ces­sory shop so there’s no need to buy a 500g tub of it. 5. Care­fully push the pis­tons back into the bores with your hands, mak­ing sure there is suf­fi­cient room in the reser­voir to take the fluid.
