How to rebuild Porsche brake calipers on a Porsche 911 912 front M brake calipers.

This video is how to rebuild Porsche 911 912 brake calipers on an early front M caliper which is found on most early cars. You can pick up the ATE brake rebuild kit which includes the new cylinder seal, the rubber dust boot, the snap ring and new pin clips. Cost is about $15 per caliper for the ATE kit or $7 for the Amazon kit (see link below), and about a liter or two of brake fluid ATE SuperBlue.


Jack up your Porsche 911 912, you can find a video on how to do this below. Next pull off the wheel and set it aside. You'll need a 19mm wrench to remove the two bolts holding on the caliper to the spindle, and a 15mm to remove the banjo nut holding on the brake fluid line to the caliper.


Getting the pistons out of the calipers will be the hardest part, you'll need an air compressor to force air into the hole left by removing the banjo nut in the Porsche 911 912 front M caliper. Have a big screwdriver or a 1/4 inch wood block set between the two pistons. As you keep the compressed air going into the caliper those two pistons will start to work their way out of their cylinders. Take your time and keep the air blowing and they will come out.


The rest is easy, new rubber seals inside, a rubber dust boot outside held on with a metal snap ring. In this Porsche 911 912 brake caliper rebuild we are not breaking the two halves apart at this time. You can finish this job in a day or weekend with plenty of beer breaks on your brakes.
