GT40-MONO is TEI's lightest caliper at 2.76kg, built for professional high-performance competition, track days, and endurance racing. A monoblock-forged caliper pairs with a slotted rotor cut in TEI's blade-pattern design and spreads 49.47cm² of clamping area across four opposed pistons, with internal fluid routing shielding the fluid path from impact and debris and R1/R2 track pad compounds available alongside the M2 metallic standard.

Fits 15–17-inch wheels. Includes caliper, rotor, brake pads, and mounting hardware.

Floating vs. Fixed Calipers

See why a fixed multi-piston caliper delivers a more direct, linear pedal feel.

Floating caliperTypical OEM

A single piston acts on the inner pad. The caliper body then slides on its guide pins to bring the outer pad into contact.

Floating caliper animation The inner piston moves first, then the caliper body floats outward before the outer pad clamps. Rotor Hydraulic pressure PistonOuter pad Inner pad Caliper body floats 1. Piston pushes inner pad2. Body floats outward3. Outer pad clamps

Two sequential steps create dead travel and a slight delay in pedal feel.

Fixed multi-piston caliperTEI design

Pistons on both sides move directly and at the same time, clamping the rotor in one controlled step.

Fixed caliper animation Opposing pistons and pads move together to clamp the rotor simultaneously. Rotor PressurePressure Inner padOuter padFixed caliper body 1. Pressure builds2. Pistons move together3. One-step clamp

Clamping force F = P × S: hydraulic pressure multiplied by total piston area. The response is direct and linear.
