A-Premium Front Disc Brake Calipers Left & Right — No Brackets, Single-Piston, M10 x 1.5, Corrosion-Resistant

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

These calipers are manufactured to meet OEM-style fitment for many classic and later-model vehicles, offering corrosion-resistant coating, M10 x 1.5 inlet and bleeder ports, and a single-piston design. They are sold as left and right units without mounting brackets and carry multiple reference numbers that align with common original and aftermarket part codes. Backed by a one-year unlimited-mileage warranty from A-Premium, these calipers are intended for drivers restoring older vehicles or replacing worn front calipers on compatible RWD platforms.

Which vehicles will these A-Premium calipers fit?

These calipers cover a broad list of rear-wheel-drive GM-based cars, trucks, and some related models across several decades. They are suitable for many passenger cars and light trucks as long as the vehicle originally used a single-piston front caliper and matches the listed years.

• Chevrolet: S10 (1982–2003), Camaro (1982–1992; 1988–1992 cast iron), Monte Carlo (1978–1988), El Camino (1978–1987), Malibu (1978–1983), Blazer/S10 Blazer (1983–1994; Blazer 1995–1997)
• GMC: Sonoma (1991–2003), Jimmy/S15 Jimmy (1983–1997), Caballero (1978–1987), S15 (1982–1990)
• Pontiac/Buick/Oldsmobile: Firebird (1982–1992), Grand Am, Grand Prix, Bonneville, Buick Century/Regal, Olds Cutlass variants — check RWD specification

What are the critical technical specifications of these calipers?

The units use a single brake piston and standard M10 x 1.5 threaded ports for both the inlet and bleeder fittings. They are pre-coated to resist corrosion and intended to match A-Premium Chevrolet caliper compatibility where referenced.

• Piston count: 1
• Inlet port: M10 x 1.5
• Bleeder port: M10 x 1.5
• Coating: anti-rust surface finish for extended service life

How do I confirm this caliper replaces my current part?

Verify fitment by comparing reference numbers, port threads, and piston configuration with your existing caliper. A-Premium lists several cross-reference numbers that align with common OE and aftermarket part codes to help ensure a correct match.

• Reference numbers include 18005263, 18005262, 8180232820, 8180232810 and related variants
• Confirm single-piston layout and M10 x 1.5 ports on your current caliper
• These units do not include mounting brackets — ensure your vehicle uses the same bracket or purchase separately

What should I expect from installation and durability?

Installation is typical for front caliper replacement: remove the wheel, detach the hydraulic line and mounting bolts, swap calipers, and bleed the brake system. The corrosion-resistant finish and factory-style fittings help provide long-term reliability when installed correctly and maintained.

• Sold as left and right front calipers without brackets
• Bleeder and inlet ports accept M10 x 1.5 fittings for straightforward hose and bleeder compatibility
• Supported by A-Premium’s one-year unlimited-mileage warranty

Who is this for: This product is aimed at owners, restorers, and mechanics working on rear-wheel-drive Chevrolet, GMC, Pontiac, Buick, and Oldsmobile vehicles from the late 1970s through the early 2000s that require OEM-style single-piston front calipers. If your vehicle matches the listed fitment, needs corrosion-resistant replacement calipers, and uses separate mounting brackets, these A-Premium front calipers provide a cost-effective, warrantied option for restoring front braking performance.
