K9002AP - 1965-1977 Porsche 911 / 912 frt brake caliper rebuild kit M Calipers w/ pistons

Caliper rebuild kit for 1965-1978 Porsche 911 Front using cast iron M calipers (with solid or vented rotors).   This kit includes CUP STYLE PISTONS.  Many of the M calipers originally used pistons with an integrated anti-knockback mechanism and a pin in each bore to engage this mechanism.   Many new OE replacement calipers omitted this mechanism and used the later updated cup style pistons.  If the calipers have been rebuilt before, sometimes the pins have been removed to accomodate the later cup style pistons.   This kit will work on all calipers that currently use the later cup style piston, or will work if the pins are removed from the bores on your original M front calipers.   

Includes:

4 boots

4 seals

4 boot retainer rings

8 crossover seals

2 bleeders

2 bleeder caps

4 pistons

1 bottle of assembly lube

Each kit services 2 calipers.   Only 1 kit required per car.
