A-Premium Front Disc Brake Caliper Pair (Left & Right) without Bracket — Single-Piston, M10x1.5 Ports

The A-Premium front left and right disc brake calipers (without bracket) are direct-replacement, single-piston calipers engineered to restore reliable front braking performance on a wide range of classic GM rear-wheel-drive vehicles.

These calipers are aftermarket replacements designed to match the mounting and hydraulic connections of original equipment on many Chevrolet, GMC, Pontiac, Buick and Oldsmobile models spanning late-1970s through the 1990s. Each unit uses a single piston, M10 x 1.5 inlet and bleeder ports, and a protective anti-rust finish to resist corrosion during storage and service. They arrive without mounting brackets so you can pair them with the correct factory-style bracket or reuse your OEM bracket when applicable.

Which vehicles will these A-Premium calipers fit?

They are intended for rear-wheel-drive applications across a long list of GM platforms. Common fits include Chevrolet S10, Camaro, Monte Carlo, El Camino, Blazer and others, plus GMC Sonoma and Jimmy, Pontiac Firebird and Grand Prix, Buick Century and Regal, and several Oldsmobile models. Always verify the year and RWD configuration before ordering.

• Compatible with many Chevrolet models 1978–1997 and Camaro 1982–1992 (cast-iron variant 1988–1992)
• GMC fits include Sonoma, S15 and Jimmy model years listed in fitment details
• Also fits Pontiac, Buick and Oldsmobile RWD models from the fitment ranges provided
• Check the reference numbers (18005263, 18005262, 18P4071, 18P4072 and equivalents) for confirmation

How do these calipers perform and what are their key specs?

Each caliper contains one piston and standard metric ports for fluid and bleeding. The units are coated to slow corrosion and come packaged for installation without extra machining or modification. They are sold without mounting brackets, so bracket compatibility must be confirmed separately.

• Single-piston design for front disc brake assemblies
• Inlet and bleeder ports: M10 x 1.5
• Anti-rust coating applied to extend service life in typical conditions
• Reference numbers supplied for cross-checking OEM compatibility

What should I know about installation and replacement parts?

These calipers are intended as direct replacements when your vehicle uses the same mounting pattern and hydraulic fittings. Because brackets are not included, you may reuse your existing bracket or purchase a compatible bracket separately. Always bleed the brake system after installation and inspect hoses and pads for wear.

• Sold without a bracket — confirm or obtain the correct bracket before installing
• Requires standard brake line connection to M10 x 1.5 port
• Bleed the system via the M10 x 1.5 bleeder port after installation
• Inspect other hardware (pads, hoses, rotor condition) when replacing calipers

Who is this for? This A-Premium caliper pair is aimed at DIY mechanics, restoration enthusiasts and professional technicians working on classic or later-model GM rear-wheel-drive cars and light trucks that match the listed years and specifications. If you need a reliable, economy-priced direct replacement caliper with standard hydraulic fittings and corrosion protection — and you already have or plan to source the correct mounting bracket — these units provide a practical option backed by A-Premium's one-year unlimited-mileage guarantee.
