GeoBrakes stocks disc brake caliper kits confirmed to fit the Gmc S15, pairing a replacement caliper at the correct left or right hand specification for the S15 with matched brake pads, caliper hardware, and in many cases a new rotor, so the entire brake corner on your Gmc S15 is restored in a single service. Every kit is confirmed for the Gmc S15 exact year, make, model, axle, and side, ships with a 100% fitment guarantee and full manufacturer warranty, and qualifies for free delivery on orders over $99.
When a caliper on the Gmc S15 seizes, leaks, or drags, the damage does not stop at the caliper. A partially seized caliper on your S15 keeps the brake pad in continuous contact with the rotor, wearing the pad unevenly and scoring the rotor surface. By the time the caliper on the Gmc S15 is identified as the fault, the pads are typically worn asymmetrically and the rotor is damaged. A caliper kit from GeoBrakes addresses every compromised component on your Gmc S15 together.
The kit for your Gmc S15 includes the disc brake caliper at the correct left or right hand specification for the S15, either new OEM-spec or quality remanufactured to the Gmc S15 piston dimension and hydraulic pressure rating, brake pads in ceramic or semi-metallic formulation matched to the S15 caliper and rotor specification, caliper hardware with slide pins, pin boots, and anti-rattle clips for correct caliper float on the Gmc S15, brake lubricant for correct pin and shim installation on your S15, and copper washers or banjo bolt seals for the brake hose connection where required by the Gmc S15 application.
A caliper kit is the right call for the Gmc S15 in three specific situations. After a seized or dragging caliper, because the pads and often the rotor on your S15 are already compromised. During a high-mileage S15 overhaul at 150,000 kilometres or more, because caliper piston seals and guide pin boots on the Gmc S15 are typically at or beyond their service life. After a brake fluid leak at the caliper, because fluid contamination of the S15 brake pad renders the friction material permanently ineffective on your Gmc S15.
New OEM-specification calipers for the Gmc S15 are manufactured from fresh materials with no prior service history, the strongest choice for S15 vehicles in high-corrosion environments. Remanufactured calipers use original Gmc S15 housings rebuilt with new pistons, seals, and boots, performing identically to new units at a lower price point for most S15 replacement applications.
Calipers for the Gmc S15 are the most position-specific brake component in the catalogue. Left and right calipers for the S15 are not interchangeable. Our vehicle selector confirms the correct caliper kit for the Gmc S15 exact year, axle position, and left or right side before purchase.
Should I replace both calipers on my Gmc S15 at the same time?
It is strongly recommended. If one caliper on the Gmc S15 has seized or leaked, the caliper on the opposite side has experienced the same conditions and age on your S15. Replacing both restores balanced, even braking and eliminates the risk of the second S15 caliper failing shortly after the first is replaced.
Do I need to bleed the brakes on my Gmc S15 after installing a caliper kit?
Yes. Opening the hydraulic circuit on the Gmc S15 to install the new caliper allows air to enter. After installation, the brake circuit on the S15 must be bled at the caliper bleeder screw to purge all air and restore a firm, consistent brake pedal on your Gmc S15.
What is the difference between a new and remanufactured caliper in the Gmc S15 kit?
A new caliper for the Gmc S15 has no prior service history and is the stronger choice for high-corrosion environments. A remanufactured caliper uses an original S15 housing rebuilt with new pistons, seals, and boots, performing identically to new at a lower price point for most Gmc S15 applications.
