2pcs Front Brake Calipers Fit For Chevrolet GMC C1500 C2500 K1500 K2500 18-4300

If your 1988-2000 Chevy or GMC C/K truck is pulling to one side under braking, dragging at the wheel, or delivering a soft, spongy pedal, seized or worn front brake calipers are the most likely culprit. This direct-fit pair restores confident, fade-resistant stopping power exactly the way the factory intended — no shimming, no guesswork, no custom brackets. Compatibility This listing covers a complete left-and-right pair of front brake calipers engineered specifically for the GMT400-platform Chevrolet and GMC full-size C/K series pickups produced from 1988 through 2000. Compatible vehicles include the Chevrolet C1500, C2500, K1500, and K2500 as well as their GMC Sierra and GMC C/K equivalents in the same family. The calipers reference OE part number 18-4300 and are designed exclusively for front axle positions. Both 2WD (C-series) and 4WD (K-series) configurations are covered, though brake system specifications can vary by trim level, factory brake package, and rotor diameter. Always verify your specific model year and sub-model using your door jamb sticker or VIN decoder before ordering. If your truck was equipped with a heavy-duty trailer tow package or an upgraded factory brake option, confirm rotor diameter compatibility as well. Key Benefits • Direct OE Replacement Fit — Bolt-on design matches factory mounting points on C1500, C2500, K1500, and K2500 without drilling, cutting, or custom adapters, cutting installation time dramatically. • Full Stopping Confidence Restored — New internal seals, pistons, and bleed ports deliver consistent, fade-resistant hydraulic clamping force across all driving conditions from daily highway commuting to towing. • Complete Pair Included — Driver side and passenger side calipers ship together so both sides of the front axle are serviced simultaneously, eliminating the uneven wear and brake pull that comes from replacing only one caliper. • New Seals and Pistons — Unlike rebuilt or remanufactured units that reuse old pistons, each caliper ships with new internal components, reducing the risk of premature fluid leaks or piston seizure. • Pre-Installed Bleeder Screw — The SAE-spec bleeder screw comes pre-installed and ready for bench bleeding or in-vehicle bleeding, so you are not hunting for hardware at the parts counter. • Eliminates Common GMT400 Brake Symptoms — Addresses pedal softness, uneven rotor wear, wheel drag, and vehicle pull that are hallmarks of aging calipers on these high-mileage C/K trucks. Technical Specifications • OE Reference Part Number: 18-4300 • Position: Front axle, driver side (left) and passenger side (right) • Piston Configuration: Single piston per caliper • Piston Diameter: OE-matched specification for C/K 1500 and 2500 platform • Bleeder Screw: Pre-installed, standard SAE thread specification • Quantity: 2 calipers per order (1 left + 1 right) • Platform Fitment: GMT400 generation, 1988-2000 • Axle Application: Front only; not intended for rear brake positions Materials and Build Quality These calipers are constructed with a cast-iron caliper body that provides the rigidity and heat dissipation characteristics needed for the heavy stopping demands of a full-size half-ton or three-quarter-ton truck. The piston bore is precision-honed to tight tolerances to ensure consistent hydraulic pressure application and long-term seal integrity. New rubber seals throughout the piston assembly are formulated to resist brake fluid degradation, thermal cycling, and the corrosive environment typical of a truck that sees road salt, mud, and towing stress. The bleeder port is machined on-center and threaded precisely to accept a standard SAE bleeder screw, preventing cross-threading during brake bleeding. The caliper bracket interfaces are machined to factory specifications so there is no rocking or misalignment when torqued to spec. Every unit is pressure-tested prior to packaging to confirm zero internal leakage before it ships to your door. Installation Guide Installing these front brake calipers on your 1988-2000 Chevy or GMC C/K truck is a straightforward two-to-three hour job for a competent DIY mechanic. Begin by safely lifting and supporting the truck on jack stands at the frame, never relying on a floor jack alone. Remove the front wheels and set them aside. Before disconnecting the brake hose, use a line wrench to crack the fitting and have a brake-line cap or clamp ready to minimize fluid loss. Unbolt the caliper bracket bolts — typically two sliding pin bolts accessed from the rear of the knuckle assembly — and slide the old caliper off the rotor. Disconnect the brake line fitting and immediately cap the line. Transfer the new caliper into position, reconnect the brake line fitting with a fresh crush washer if applicable, and torque the bracket bolts to factory specification (typically 38 ft-lb for slider pins, 129 ft-lb for bracket bolts on these platforms — always verify with a factory service manual for your exact year). Install new brake pads if they have not been recently replaced, retract the new piston fully into its bore using a C-clamp or caliper piston tool before seating the pads. Reinstall the wheel and torque lug nuts to spec. Repeat on the opposite side. Bench-bleed or in-vehicle bleed the system starting from the farthest caliper (passenger rear) and working toward the master cylinder. Pump the brake pedal repeatedly until firm before moving the vehicle. Check the master cylinder reservoir level and top off with DOT 3 fluid as needed. Perform a slow-speed test stop before returning to normal driving.
