Every kit is confirmed for the Mazda Rx 8 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 Mazda Rx 8 seizes, leaks, or drags, the damage does not stop at the caliper. A partially seized caliper on your Rx 8 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 Mazda Rx 8 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 Mazda Rx 8 together.
The kit for your Mazda Rx 8 includes the disc brake caliper at the correct left or right hand specification for the Rx 8, either new OEM-spec or quality remanufactured to the Mazda Rx 8 piston dimension and hydraulic pressure rating, brake pads in ceramic or semi-metallic formulation matched to the Rx 8 caliper and rotor specification, caliper hardware with slide pins, pin boots, and anti-rattle clips for correct caliper float on the Mazda Rx 8, brake lubricant for correct pin and shim installation on your Rx 8, and copper washers or banjo bolt seals for the brake hose connection where required by the Mazda Rx 8 application.
A caliper kit is the right call for the Mazda Rx 8 in three specific situations. After a seized or dragging caliper, because the pads and often the rotor on your Rx 8 are already compromised. During a high-mileage Rx 8 overhaul at 150,000 kilometres or more, because caliper piston seals and guide pin boots on the Mazda Rx 8 are typically at or beyond their service life. After a brake fluid leak at the caliper, because fluid contamination of the Rx 8 brake pad renders the friction material permanently ineffective on your Mazda Rx 8.
New OEM-specification calipers for the Mazda Rx 8 are manufactured from fresh materials with no prior service history, the strongest choice for Rx 8 vehicles in high-corrosion environments. Remanufactured calipers use original Mazda Rx 8 housings rebuilt with new pistons, seals, and boots, performing identically to new units at a lower price point for most Rx 8 replacement applications.
Calipers for the Mazda Rx 8 are the most position-specific brake component in the catalogue. Left and right calipers for the Rx 8 are not interchangeable. Our vehicle selector confirms the correct caliper kit for the Mazda Rx 8 exact year, axle position, and left or right side before purchase.
Should I replace both calipers on my Mazda Rx 8 at the same time?
It is strongly recommended. If one caliper on the Mazda Rx 8 has seized or leaked, the caliper on the opposite side has experienced the same conditions and age on your Rx 8. Replacing both restores balanced, even braking and eliminates the risk of the second Rx 8 caliper failing shortly after the first is replaced.
Do I need to bleed the brakes on my Mazda Rx 8 after installing a caliper kit?
Yes. Opening the hydraulic circuit on the Mazda Rx 8 to install the new caliper allows air to enter. After installation, the brake circuit on the Rx 8 must be bled at the caliper bleeder screw to purge all air and restore a firm, consistent brake pedal on your Mazda Rx 8.
What is the difference between a new and remanufactured caliper in the Mazda Rx 8 kit?
A new caliper for the Mazda Rx 8 has no prior service history and is the stronger choice for high-corrosion environments. A remanufactured caliper uses an original Rx 8 housing rebuilt with new pistons, seals, and boots, performing identically to new at a lower price point for most Mazda Rx 8 applications.
