Thank you. Sounds like a medium complexity job. I was hoping for something simple a dummy can do such as taking the boot out or removing the wheel and adjusting that calibration star thing.
Looks like I may have to take it to the shop.
It’s actually not that difficult.
Tools required, socket set and Allen/Hex bits.
Loosen the wheel bolts.
Jack the car and place an axle stand.
Take off the wheel.
Locate the disc lock stud, fit in an Allen bit, smack it with a hammer to help loosen it, then unscrew. Place it with the wheel bolts.
Insert a screwdriver/lever between the disc hat and anti rattle clip. Press the center of the clip and it’ll release. Put it with the wheel bolts.
Pull off the plastic plugs on the caliper sliders, insert an Allen bit and remove. Place somewhere clean.
IMPORTANT. CLEAN YOUR HANDS OR CHANGE GLOVES. The sliders should be lubricated with silicone grease, you don’t want that stuff anywhere near the friction parts of your brakes.
Remove the caliper and tie it up out of the way.
Use a socket and breaker bar to undo the carrier bolts. Place both with the wheel bolts..
Chock a front wheel and make sure the handbrake is off.
Hit the center of the disc, the hat, with an impact hammer/ rubber or plastic hammer, to shock it loose. Hold the disc 180degrees apart and wiggle it free. If someone has set the disc/shoe clearance too tight, it may be slightly lipped, in which case you’ll have to back off the adjuster.
The two shoes are held by an Allen clip and spring. The clip often pulls through the backplate. The simple fix consists of two stainless washers, a nyloc nut and a stainless bolt, or set screw.
The nyloc nut and one washer, goes behind the disc. Reuse the spring, with the washer and bolt, to hold the shoe in the correct place. Do NOT tighten it fully, there needs to be some play. The nyloc nut prevents it loosening and the spring holds the shoe flush to the backplate.
Ensure the adjuster moves freely. Do not oil, or grease it, both clog with dirt and jam it.
Refit the disc and add its lock screw.
Tighten the adjuster fully until the disc won’t move.
Back it off two clicks, ensure the disc rotates without binding, if it binds, back it one more click. It can help to pull the handbrake on/off several times to center the shoes.
Clean the bolt threads and refit the carrier, a little copper, or aluminium, grease on the threads if you have it.
Refit the caliper. If the sliders are dirty, clean and polish them. Do not sand them, wire brush, or blast them clean. They’re stainless steel, polish them. Smear a little silicone grease on the sliders if you have it. Do NOT use copper grease, it is not a lubricant, it absorbs water and dries out. Replace the plastic plugs.
Refit the anti rattle clip, put the outer flats against the carrier, compress the center and the two lock clips slide in.
Check the disc locating Allen screws is tight.
Refit the wheel, tighten and do the same on the other side.
There are YouTube videos on how to replace the shoes, but if just replacing the clips with bolts, you don’t actually have to remove the shoes.
