Troubleshooting Porsche 914 Brake Caliper Problems: Here's How to

Among the parts of your Porsche 914's braking system, it is the brake caliper that slows down the wheels by generating friction with the rotors. The caliper is made up of a housing, bleeder valve, hydraulic flex hose port, dust boot, and piston. When the calipers become defective, they will not be able to efficiently push the brake pads to the rotor, thus affecting the vehicle's ability to stop at the right time. This can result in a fatal accident, so it's important that you know the signs of brake caliper failure and the ways to troubleshoot them.

Sticking brake caliper

When your Porsche 914 brake caliper sticks, the brake pads can wear out prematurely. If your Porsche's caliper is outfitted with slide bolts, they can stick as well. But the good thing about these bolts is they can be cleaned and re-lubricated once they stick, so they can be reused.

The easiest way to diagnose sticking brake calipers is to start the vehicle, set it in gear, or drive on a flat ground. If your ride comes with a standard transmission, release the clutch slowly; if it's equipped with an automatic transmission, release the brake pedal. If you notice that the vehicle rolls slowly, try to brake hard. Again, let your ride move forward slowly. If the vehicle feels sluggish or if it fails to move at all after applying the brakes hard, this means the calipers are sticking.

Problems with caliper guide pin

If you're experiencing problems with your brakes, the caliper guide pins could be the culprit, but the only way to be sure is to do a careful inspection. The process is quite difficult because it's pretty much like you're replacing the brake pads yourself. It involves lifting your Porsche, taking the tires off, removing the caliper, and checking the caliper housing. You need to carefully inspect the caliper for corrosion and improper lubrication.

Well-installed guide pins are easy to take out using a screwdriver and with just a few light taps from a hammer. If you find it hard to remove the guide pins because they are stuck or they have rusted in place, then they are the culprit for your braking problems.
