we hit 60k miles recently, so before we take our usual road trip, DH did the whole rear brake clean and adjust job on our prius. and i took pictures. this job is something that can be done by someone who is fairly DIY competent. that is, a novice or anyone who thinks they might mess things up is strongly discouraged from trying this. there are several things that can go wrong in this process that could lead to problems either immediately or down the road. that out of the way, here's what you do. 1. lift the car. safety first- use proper supports. remove the wheel. 2. remove the brake drum. chances are it will be tight. use two bolts to push it off as shown: 3. sandpaper the friction surface of the drum with aluminum oxide sandpaper- 80 grit wet or dry is what DH is using here. see how shiny that surface is? that's glazing. the glazing will be removed as well as brake dust. NEVER sand in the direction parts are moving. do not sand around the long surface, sand perpendicular to it. if you sand parallel to the long surface, you can score the surface, which you really do not want to do. 4. next up is the rest of the brake assembly. it is filthy. rear shoes looking very good at 63k but they are glazed. 7. shoes get sanded to remove glazing, too. again never sand in the direction of parts movement. always perpendicular to it. same reasons as for the drum. now cleaned of glaze, will brake more efficiently. 8. and the rest of the cleaning part: brake parts cleaner removes brake dust built up all over the place don't forget the drum 9. reassemble brake assembly. DH always makes sure to put the drum back on in exactly the same position as when he took it off. make sure it is all the way back on. spin assembly, pull gently on parking brake cable and flex it to stop spinning. if it stops, then all is well. 10. adjust rear brakes. this is trickier than what's been done so far. where DH has the screwdriver in this picture, there is a rubber plug that reveals a hole through to the star adjuster screw. start by finding the adjuster screw with your screwdriver. now that you know where it is, spin the drum. listen for any light drag. adjust one click forward. listen again for light drag. continue doing this until you hear a very slight drag sound. then stop making your adjustments. some of you are probably wondering why you would want the brakes to drag slightly. remember this is an adjustment point, and the self-adjusters will readjust the shoes again when you step on the brake. it has been about 30k since the last time DH did a clean and adjust on our prius. the left side was in fine adjustment, but the right side took eighteen clicks to adjust. those self adjusters aren't always perfect. i was getting a slight wobble (only on hard braking) as a result of this adjustment problem. now things are back to normal.
