Do I need to open brake fluid reservoir when changing pads?
Once the brake caliper piston has been fully retracted, you can re-cap the brake fluid reservoir. It’s not a good idea to leave the cap off of your brake fluid reservoir for any longer than is absolutely necessary. Debris or even water may find its way into your brake’s hydraulic system.
Do you need to change rotors with brake pads Porsche?
Many Porsche dealerships will insist on replacing the brake pads and rotors at the same time. While we are often skeptical of dealership service centers, we generally agree. Typically on a Porsche, by the time the brake pads need to be replaced, your car has eaten through a significant amount of brake rotor material.
Why do Porsche brakes squeak?
Brake squeal is a result of a condition called stick-slip, [which causes] microscopic vibrations that create noise to be broadcast by the brake rotor which acts as a speaker. Necessity dictates that the Porsche brake system be designed with large rotors and pads.
Do I pump brakes after changing pads?
As mentioned, you always start car, pump up brakes after a pad change – simply to move piston/pad combo back out into contact with rotor after you have retracted the piston fully during swap. This should take like 3-5 pumps on the pedal max, not 5 minutes of pumping.
