Clamp the brake pads against the rotor at the front right wheel with the A1 CARDONE brake caliper 18-B4938, a remanufactured, unloaded disc brake caliper supplied with its mounting bracket. It fits many vehicles, among them the 2004-2008 Chevrolet Colorado, 2004-2008 GMC Canyon and 2007-2008 Isuzu I-290. See the "Vehicles it fits" section for the full list and engine details.
CARDONE remanufactures each caliper to strict quality and performance standards and fits it with brand-new components. It then treats the caliper with a specially formulated rust inhibitor and keeps the original equipment finish.
- Pressure-tested: every unit is 100% pressure-tested, designed to deliver consistent brake performance.
- New seals and durable pistons: the rubber seals are replaced with new high-temperature EPDM rubber. The pistons are built to resist cracking and pitting and to handle heavy loads.
- Bleeder and port protection: a new bleeder screw allows easy bleeding and gives a positive seal. A plastic cap plug protects every brake port thread until installation.
- Hardware: depending on the application, CARDONE also supplies new banjo bolts, washers, stainless steel hardware clips and mounting pins.
This caliper is sold unloaded, so brake pads are not included. It is sold individually for the front right position, and replacing both front calipers together is recommended for even, balanced braking. CARDONE's remanufacturing process cuts the energy and raw material needed to make a new part by 80%.
