914World.com _ 914World Garage _ Front Brake Piston Retaining Clips

Posted by: aggiezig Jun 6 2018, 09:51 PM

Quick, easy question. This is my first time working with 914 calipers so these retaining clips are throwing me off. Which way do these clips get installed in the caliper? Four pegs in to the piston (push them on) or four pegs out towards the pad?

Also, there appears to be a "left" and "right" clip. Which way should these be installed in the caliper? I found a diagram on Pelican's site but it only shows the clip on one half of the caliper.

Thanks in advance

You should have 4 clips, 2 for each caliper.
The tabs push into the caliper piston and the angled edge fits the angled cut in the piston.
When calipers are assembled and installed the clips need to mirror each other on the calipers and the clips go toward the leading edge of the brake pads.

The clip and piston you picture is correct for a rotor with a clockwise rotation when the car is moving forward.

I'm sorry that is not a great description but I don't know which caliper halve you are picturing so I don't know how to describe it better.

The angled cut in the pistons is to reduce the pressure on the leading edge of the brake pads, so the pads wear evenly. The normal braking force would otherwise cause the pads to cant slightly in the caliper and wear at an angle.

Thanks, Jim. As clear as mud!
