Brake Caliper Service, Fitting & Repair Parts
Brakes International & Brakeparts.co.uk are Budweg’s appointed UK national distributor and stock in excess of 8000 calipers. Budweg Caliper have been re-manufacturing brake calipers since 1978. Today, Europe’s largest and most respected caliper re-manufacturer, they produce over a million calipers per year. Unlike many re-conditioners, Budweg renew every worn internal component; this ensures that a Budweg caliper is every bit as good and often better than a new caliper. We also carry an alternative range of calipers sourced from TRW Lucas, FTE and Brake Engineering.
Calipers are of two types, floating or fixed. A fixed caliper does not move relative to the disc and is thus less tolerant of disc imperfections. It uses one or more pairs of opposing pistons to clamp from each side of the disc, and is more complex and expensive than a floating caliper. A floating caliper (also called a “sliding caliper”) moves with respect to the disc, along a line parallel to the axis of rotation of the disc; a piston on one side of the disc pushes the inner brake pad until it makes contact with the braking surface, then pulls the caliper body with the outer brake pad so pressure is applied to both sides of the disc. Floating caliper (single piston) designs are subject to sticking failure, caused by dirt or corrosion entering at least one mounting mechanism and stopping its normal movement. This can lead to the caliper’s pads rubbing on the disc when the brake is not engaged or engaging it at an angle. Sticking can result from infrequent vehicle use, failure of a seal or rubber protection boot allowing debris entry, dry-out of the grease in the mounting mechanism and subsequent moisture incursion leading to corrosion, or some combination of these factors. Consequences may include reduced fuel efficiency, extreme heating of the disc or excessive wear on the affected pad. A sticking front caliper may also cause.
