A-Premium Disc Brake Calipers Front Left & Right without Bracket — Single-Piston, Anti-Rust

A-Premium front left and right disc brake calipers (without bracket) are direct-replacement, single-piston calipers engineered to restore front braking function on a wide range of rear-wheel-drive GM and related vehicles from the 1970s through the early 2000s.

These A-Premium calipers are built for owners restoring or maintaining classic and later-generation GM cars and trucks who need reliable, corrosion-resistant calipers that match factory-style fitment and hydraulic connections. They come coated with an anti-rust finish, use standard M10 x 1.5 inlet and bleeder ports, and are sold in left and right side units without the mounting bracket.

Which vehicles will these calipers fit?

These calipers are designed for a broad range of rear-wheel-drive GM-based models and a few related truck and coupe platforms. Fitment spans many Chevrolet, GMC, Pontiac, Buick, Oldsmobile, Isuzu and other badge-engineered models, mainly RWD configurations.

• Chevrolet: S10 (1982–2003), Camaro (1982–1992; 1988–1992 cast iron caliper option), Monte Carlo, El Camino, Malibu, Blazer, S10 Blazer, LLV
• GMC: Sonoma (1991–2003), S15, Jimmy, Caballero
• Pontiac, Buick, Oldsmobile, Isuzu and others across late 1970s–1990s model years (RWD only)

What are the technical specifications I should know?

These calipers are single-piston units with M10 x 1.5 hydraulic fittings for both the inlet and bleeder ports, matching common factory plumbing on the covered vehicles. The anti-corrosion coating helps extend service life compared with bare cast parts.

• Brake piston count: 1 piston
• Inlet port size: M10 x 1.5; Bleeder port: M10 x 1.5
• Reference/OE cross numbers: 18005263, 18005262, 8180232820, 8180232810, 184071, 184072 and variants
• Coated finish for enhanced rust resistance

How do I confirm this caliper is the right replacement for my vehicle?

Compare your vehicle’s year, model, axle drive (RWD only for this caliper) and the OEM reference numbers with the list provided. Also verify that your existing caliper uses a single piston and M10 x 1.5 fittings; if your car used a cast-iron variant for certain years (notably some Camaro years), check which caliper style you require.

• Confirm RWD axle—these units do not fit front-wheel-drive variants
• Match OE reference numbers or compare inlet/bleeder thread size and piston count
• Inspect whether your model used cast-iron calipers in specific years (e.g., Camaro 1988–1992)

What does the purchase include and what warranty applies?

Each sold caliper is a single left or right-side unit supplied without the mounting bracket. A-Premium backs these calipers with a one-year unlimited-mileage guarantee to cover manufacturing defects and give buyers confidence during installation and initial service life.

• Sold as individual left or right side disc caliper (bracket not included)
• One-year unlimited-mileage A-Premium warranty
• Coated finish and factory-compatible hydraulic ports for straightforward installation

Who is this for: This A-Premium front brake caliper is aimed at classic-car restorers, DIY mechanics, and service professionals working on rear-wheel-drive Chevrolet, GMC, Pontiac, Buick, Oldsmobile and related vehicles from the late 1970s through the 1990s and early 2000s who need a direct-fit, single-piston replacement without a bracket. Choose this caliper when you require OE-referenced fitment, corrosion resistance, and a backed one-year guarantee for peace of mind during road use and maintenance.
