Had a sticky piston on the LH side resulting in pulling to the right, found the dust boot was damaged allowing the piston to stick.

Freed it using silicon grease but only a temp fix so...

3 seal sets £35
New brembo front discs and mintex pads for £90 and bit of my time.

Seals are easy to change, you might have problems getting the pistons out so go to a garage and ask them to remove the pistons with an air gun though you could prob pull them out with a set of grips.

Tip: grab the dust boot and pull, the circlip will come out also, use a pick to remove the main hydraulic seal and clean the recess.

I took the oportunity to totally strip and clean mine but no need to go that far.

For rebuild you use caliper grease 08887-01206 at about £8 for a tube. Lube the pistons and seals and a squirt more in the dust cap.

Cheers, going to the workshop later to torque the bolts that hold the 2 halfs of the caliper. .. remember to use thread lock!

Once they are installed ill give everything another coat of paint and install them next week when I have more time. Using the yaris in between.

Wow awesome write up!
Great way to slide the piston back in. Always struggeling getting the piston back in. But the way you show with the piece of plastick paper is a great way to do the job thanks!
