Trelleborg, Sweden – Trelleborg Sealing Solutions has come up with a solution to the problem of car-braking noise and vibration, which can be tailored to any sliding caliper brake system.
The design, it describes as a carefully engineered “layer cake” of stainless steel and rubber holding the brake pad in place.
Sandwiched between the brake pad “ear” and contact points in the anchor bracket, the abutment clip dampens the clunk or low-frequency noise by decoupling the pad ear, isolating it from the anchor bracket and preventing in-plane energy from being transmitted to the calipers.
It also enables the easy retraction of the pad on the release of brake pressure, reducing the risk of residual drag.
Abutment clips have traditionally been made from uncoated stainless steel, but as car engines have become quieter, there has been a growing demand for noiseless braking systems with rubber-coated clips.
