When a caliper on the Lexus Rx450h seizes, leaks, or drags, the damage does not stop at the caliper. A partially seized caliper on your Rx450h 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 Rx450h 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 Rx450h together.
The kit for your Lexus Rx450h includes the disc brake caliper at the correct left or right hand specification for the Rx450h, either new OEM-spec or quality remanufactured to the Lexus Rx450h piston dimension and hydraulic pressure rating, brake pads in ceramic or semi-metallic formulation matched to the Rx450h caliper and rotor specification, caliper hardware with slide pins, pin boots, and anti-rattle clips for correct caliper float on the Lexus Rx450h, brake lubricant for correct pin and shim installation on your Rx450h, and copper washers or banjo bolt seals for the brake hose connection where required by the Lexus Rx450h application.
A caliper kit is the right call for the Lexus Rx450h in three specific situations. After a seized or dragging caliper, because the pads and often the rotor on your Rx450h are already compromised. During a high-mileage Rx450h overhaul at 150,000 kilometres or more, because caliper piston seals and guide pin boots on the Lexus Rx450h are typically at or beyond their service life. After a brake fluid leak at the caliper, because fluid contamination of the Rx450h brake pad renders the friction material permanently ineffective on your Lexus Rx450h.
New OEM-specification calipers for the Lexus Rx450h are manufactured from fresh materials with no prior service history, the strongest choice for Rx450h vehicles in high-corrosion environments. Remanufactured calipers use original Lexus Rx450h housings rebuilt with new pistons, seals, and boots, performing identically to new units at a lower price point for most Rx450h replacement applications.
Calipers for the Lexus Rx450h are the most position-specific brake component in the catalogue. Left and right calipers for the Rx450h are not interchangeable. Our vehicle selector confirms the correct caliper kit for the Lexus Rx450h exact year, axle position, and left or right side before purchase.
Should I replace both calipers on my Lexus Rx450h at the same time?
It is strongly recommended. If one caliper on the Lexus Rx450h has seized or leaked, the caliper on the opposite side has experienced the same conditions and age on your Rx450h. Replacing both restores balanced, even braking and eliminates the risk of the second Rx450h caliper failing shortly after the first is replaced.
Do I need to bleed the brakes on my Lexus Rx450h after installing a caliper kit?
Yes. Opening the hydraulic circuit on the Lexus Rx450h to install the new caliper allows air to enter. After installation, the brake circuit on the Rx450h must be bled at the caliper bleeder screw to purge all air and restore a firm, consistent brake pedal on your Lexus Rx450h.
What is the difference between a new and remanufactured caliper in the Lexus Rx450h kit?
A new caliper for the Lexus Rx450h has no prior service history and is the stronger choice for high-corrosion environments. A remanufactured caliper uses an original Rx450h housing rebuilt with new pistons, seals, and boots, performing identically to new at a lower price point for most Lexus Rx450h applications.
