Removing and installing pads — VW

If the pads are to be used again they must be marked on removal and installed in the same position otherwise the brakes will pull unevenly.

Knock retaining pins out. On calipers with 14 mm thick pads, remove retaining clip beforehand.

Pulling out the outer brake pad. The outer brake pad is located by a projection on the floating frame. To remove it, the floating frame must be pressed out-wards.

Press piston into the cylinder using the special tool.

Caution:
Before pressing piston back, siphon some fluid out of the reservoir as otherwise, if additonal fluid has been added in the meantime, it may overflow and cause damage.
Use a bleeder bottle or a soft plastic bottle to siphon the fluid and keep the container for this job only. Brake fluid is poisonous and must on no account be sucked out with a hose.
