Complete set of genuine Mercedes-Benz brake calipers removed from a 1999 R129 SL500. This is the late-model big brake setup — the larger brakes fitted to the 1999–2002 SL500 and SL600 — and the bolt-on brake upgrade for the R129.

• Front: Brembo 4-piston calipers (left + right pair) for the larger 334mm front rotors
• Rear: ATE calipers (left + right pair) for 300mm rear rotors

FITMENT

Fits all R129 models (1989–2002) — this is the upgrade for earlier cars running the smaller brakes. Rotors are not included: the fronts run 334 x 32mm rotors (A 129 421 21 12 solid / A 129 421 23 12 cross-drilled) and the rears run 300 x 22mm rotors (A 129 423 03 12 / A 129 423 05 12). Note: 17-inch or larger wheels are required to clear the front Brembo calipers.
