Patent number: 11959522Abstract: A brake assembly having a brake carrier, a caliper, first and second brake pads, a pad retraction spring, and a first stop surface. The pad retraction spring urges the first and second brake pads in a direction away from a rotor plane. A first supporting portion of the pad retraction spring is configured to abut the first stop surface to inhibit the pad retraction spring from entering a partially enclosed volume.Type: GrantFiled: June 27, 2023Date of Patent: April 16, 2024Assignee: Meritor Heavy Vehicle Braking Systems (UK) LimitedInventors: Sean Cleary, Alex Szafnauer

Patent number: 11879511Abstract: A disc brake assembly having brake pads, a brake carrier, a caliper, and an actuating arrangement. The caliper is slidable with respect to the brake carrier for clamping and release of a rotor by the brake pads. The actuating arrangement is configured to selectively move the caliper and the brake carrier relative to each other generally transverse to a first longitudinal axis so as to lock or inhibit sliding of the caliper relative to the carrier.Type: GrantFiled: February 17, 2022Date of Patent: January 23, 2024Assignee: Meritor Heavy Vehicle Braking Systems (UK) LimitedInventors: Alex Szafnauer, Sean Cleary, Tim Smith, Anthony Williams, Paul Thomas

Publication number: 20230105818Abstract: A drum brake assembly that includes a brake drum, first and second brake shoes, a cam shaft, a first tappet, a second tappet, and a wear adjuster mechanism. The wear adjuster mechanism has a cross shaft and a sensor. The sensor is configured to detect rotation of the cross shaft about a longitudinal axis to monitor wear of the first and second brake shoes and a braking surface of the brake drum.Type: ApplicationFiled: August 22, 2022Publication date: April 6, 2023Applicant: Meritor Heavy Vehicle Braking Systems (UK) LimitedInventors: Alex Szafnauer, Sean Cleary

Publication number: 20220299075Abstract: A brake assembly including a caliper that has a first guide bore, a brake carrier arranged to receive a brake pad, a first guide pin secured to the brake carrier, and a first lock arrangement. The first lock arrangement is operable to selectively inhibit relative sliding between the caliper and the brake carrier.Type: ApplicationFiled: March 18, 2022Publication date: September 22, 2022Applicant: Meritor Heavy Vehicle Braking Systems (UK) LimitedInventors: Alex Szafnauer, Sean Cleary, Tim Smith, Anthony Williams, Paul Thomas
-
Publication number: 20220299073Abstract: A disc brake having a brake carrier, a guide surface and a travel limiting arrangement. A first brake pad assembly is configured to slide relative to the guide surface. The travel limiting arrangement engages the guide surface and is configured to inhibit sliding of the first brake pad assembly relative to the guide surface that is above a pre-determined amount.Type: ApplicationFiled: March 15, 2022Publication date: September 22, 2022Applicant: Meritor Heavy Vehicle Braking Systems (UK) LimitedInventors: Sean Cleary, Alex Szafnauer
