GeoBrakes stocks disc brake caliper kits confirmed to fit the Lexus Gs400, pairing a replacement caliper at the correct left or right hand specification for the Gs400 with matched brake pads, caliper hardware, and in many cases a new rotor, so the entire brake corner on your Lexus Gs400 is restored in a single service. Every kit is confirmed for the Lexus Gs400 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 Lexus Gs400 seizes, leaks, or drags, the damage does not stop at the caliper. A partially seized caliper on your Gs400 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 Lexus Gs400 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 Lexus Gs400 together.
The kit for your Lexus Gs400 includes the disc brake caliper at the correct left or right hand specification for the Gs400, either new OEM-spec or quality remanufactured to the Lexus Gs400 piston dimension and hydraulic pressure rating, brake pads in ceramic or semi-metallic formulation matched to the Gs400 caliper and rotor specification, caliper hardware with slide pins, pin boots, and anti-rattle clips for correct caliper float on the Lexus Gs400, brake lubricant for correct pin and shim installation on your Gs400, and copper washers or banjo bolt seals for the brake hose connection where required by the Lexus Gs400 application.
A caliper kit is the right call for the Lexus Gs400 in three specific situations. After a seized or dragging caliper, because the pads and often the rotor on your Gs400 are already compromised. During a high-mileage Gs400 overhaul at 150,000 kilometres or more, because caliper piston seals and guide pin boots on the Lexus Gs400 are typically at or beyond their service life. After a brake fluid leak at the caliper, because fluid contamination of the Gs400 brake pad renders the friction material permanently ineffective on your Lexus Gs400.
New OEM-specification calipers for the Lexus Gs400 are manufactured from fresh materials with no prior service history, the strongest choice for Gs400 vehicles in high-corrosion environments. Remanufactured calipers use original Lexus Gs400 housings rebuilt with new pistons, seals, and boots, performing identically to new units at a lower price point for most Gs400 replacement applications.
Calipers for the Lexus Gs400 are the most position-specific brake component in the catalogue. Left and right calipers for the Gs400 are not interchangeable. Our vehicle selector confirms the correct caliper kit for the Lexus Gs400 exact year, axle position, and left or right side before purchase.
Should I replace both calipers on my Lexus Gs400 at the same time?
It is strongly recommended. If one caliper on the Lexus Gs400 has seized or leaked, the caliper on the opposite side has experienced the same conditions and age on your Gs400. Replacing both restores balanced, even braking and eliminates the risk of the second Gs400 caliper failing shortly after the first is replaced.
Do I need to bleed the brakes on my Lexus Gs400 after installing a caliper kit?
Yes. Opening the hydraulic circuit on the Lexus Gs400 to install the new caliper allows air to enter. After installation, the brake circuit on the Gs400 must be bled at the caliper bleeder screw to purge all air and restore a firm, consistent brake pedal on your Lexus Gs400.
What is the difference between a new and remanufactured caliper in the Lexus Gs400 kit?
A new caliper for the Lexus Gs400 has no prior service history and is the stronger choice for high-corrosion environments. A remanufactured caliper uses an original Gs400 housing rebuilt with new pistons, seals, and boots, performing identically to new at a lower price point for most Lexus Gs400 applications.
