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

SR4-Explore is the rear match for TEI's S-series front kits, built for vehicles with a factory electric parking brake — it carries its own EPB motor, so the parking brake keeps working exactly as it did from the factory. Four opposed pistons spread 24.61cm² of clamping area across a two-piece forged caliper for a firmer, more balanced rear brake than the OEM caliper it replaces.
Fits 18–21-inch wheels. Includes caliper, rotor, brake pads, and mounting hardware.
