Mercedes Actros MP4/MP5 Front Left Brake Caliper A9604201201 Wabco 6403220730 Brake Calipers

Description:
Genuine Mercedes-Benz / WABCO front left disc brake caliper for heavy commercial trucks. This unit is the MAXX 22 type caliper used on Euro 6 Mercedes Actros MP4/MP5, Antos and Arocs models. OEM Mercedes reference numbers include A9604201201 (A 960 420 12 01) and supersessions A0054201383 / A0054203783, while the WABCO catalogue number is 6403220730 MAXX22. According to WABCO product data, this caliper is designed for 45 mm brake discs, left side mounting, six‑bolt carrier and is fitted with pads from factory.

The caliper was removed from a running Euro 6 Actros MP truck and was checked on the vehicle before dismantling – braking function was tested, there were no leaks and the sliding mechanism operated smoothly. Visual inspection shows typical working wear, paint loss and surface corrosion on exposed metal parts, but no cracks or structural damage to the cast housing. Guide pins move freely and dust boots appear intact. The unit is sold complete with used pads as shown; although there is remaining material, for safety we recommend fitting new pads and hardware kit during installation.

This MAXX 22 front LH caliper fits a wide range of Mercedes-Benz Euro 6 heavy trucks using the same axle and brake package, including at least:
- Mercedes-Benz Actros MP4 (2012–2019) 4x2/6x2/6x4 tractors and rigids, selected front axles
- Mercedes-Benz Antos (2012–on) distribution chassis with MAXX22 front brakes
- Mercedes-Benz Arocs (2013–on) construction trucks with compatible axle
Compatibility should always be confirmed by matching OE number A9604201201 or WABCO 6403220730 to your existing caliper or VIN‑based dealer information.
