Yaris T sport rear brakes service

[corradovr6]

Yesterday's project was to replace the rear brake pads.  Not a simple as it looks as the pads have a thin retaining spring.  Further issues:

Pad retaining pins rusted

Caliper sliding pistons seized, so pads worn at an angle

 

Turns out it wasn't too difficult.  Sprayed the 14mm bolts with wd40 a few times, as well as the pad locking pins.  Brushed off the loose corrosion and then used thin pliers to carefully remove the wire springs.  Carefully tapped the locking pins with a small hammer and drift from the inside.  Its important not to hit them too hard as the caliper itself could fracture.

Removed the old springs, removed the caliper and freed up the frozen caliper slider piston by slowly compressing it into a 28mm socket on the other side with a g-clamp

Cleaned the pistons, red rubber grease on them and then refitted. Slide nice and smoothly.  Rubber boots were fine and with no splits.

Copper slip on the mounting bolts and brake grease on the pads and locking pins.  The pad retaining wires are a bit fiddly to reinstall especially when the light is fading!  I suspect that these have never been changed and may very well have been the original pads.  

Handbrake shoes seemed fine - just slight rubbing on the inside of the drum so these were left alone.  Didn't take many pics unfortunately but will post the ones i do have shortly. 

Hope that helps

Did the RHS the next day. Pad retaining pins were a real mission. Seized in place. Sprayed with shock unlock which is absolutely rubbish. Wd40, contact cleaner, freezer spray and more wd40. Tapped with a centre punch and heavy hammer to remove the pins. Took about 2 hours solid work to remove. 

Used 

Anyway, pics attached, which i hope are useful

Can't seem to be able to add any more for some reason..

some more pics.  USed red rubber grease on the pistons in contact with the rubber boots, and copper slip on the threads.

Also, the socket was used to gentle release the frozen slider piston with the g clamp.  RRG on both and checked that they were moving freely.  All seems good now!

Polished up the wheel nuts on one side too - small details do make a difference i feel.
