AJP/Braktec 4 Pot Calliper - Halves O-ring
O-ringused to seal the two halves of the cailliper together on the AJP & Braktec 4 pot caliper
4mm inner diameter x 2.0mm cross section EDPM rubber.
These are very difficult to fit, forcing the pistons past the seals will damage the seals, please read the fitting guide in the description.
For inexperienced mechanics or anyone who lacks patience, you're probably better buying a new calliper instead.

Fitting guide:
You need to make sure the seal groves are spotlessly clean and free from any dirt or corrosion, we use a plastic o-ring pick tool to scrape the grove clean without scratching the aluminium.
Then lubricate the seals with a silicon based grease or Castrol red rubber grease before fitting.
To get the pistons in you have to take your time and slowly wiggle the pistons around in the bore until the seal goes all the way around the piston, the piston will then easily slide into the calliper with finger pressure.
Do not force the piston into the calliper, if it needs more than finger pressure, the seal hasn't gone over the edge of the piston and forcing it in will cut the seal.
