Fitment Notes

• Always match OEM reference number(s) and vehicle details before ordering. Confirm exact fitment using VIN, engine code, or chassis number if multiple variants exist.
• This is a rear-axle caliper repair kit for ATE-specification brake systems with a 35mm piston bore. Confirm your caliper is ATE and the piston bore is 35mm before ordering — other manufacturers (Bendix, Girling, Teves variants) and other bore sizes will not fit.
• Covers a wide spread of Mercedes-Benz chassis (W114, W115, W116, W123, W124, W126, R107, R129) plus Opel Senator, Chevrolet Senator and Volvo 140/160/850 applications sharing the same rear caliper specification.

Installation / Use / Maintenance Tips

• Caliper repair kits must be fitted by a qualified brake technician — incorrect assembly can cause brake failure.
• Clean the caliper bore thoroughly and inspect for pitting, scoring or corrosion before reassembly; replace the caliper body if damaged.
• Lubricate new seals with the correct brake-assembly paste or clean brake fluid only — never use petroleum-based grease.
• Bleed the brake circuit fully after reassembly and check for leaks under pressure before road testing.
• Replace brake fluid with the correct DOT specification for the vehicle and check handbrake operation where the rear caliper incorporates the parking brake.

Common Questions

Will this rear caliper repair kit fit my Mercedes-Benz?
This part (CK38.0981) is listed for the fitments shown on this page. Confirm by matching the fitment details, verifying the caliper is ATE with a 35mm bore, and checking VIN/engine/chassis information where variants exist.

What OEM part numbers does this cross-reference?
Cross-reference numbers are listed in the OEM Reference Numbers section above. Match at least one to your original part before ordering.

Why are the OE numbers Opel and Saab if this fits Mercedes-Benz as well?
Caliper repair kits are grouped by caliper specification (manufacturer, bore size, position) rather than by a single vehicle OE number. The listed Opel and Saab part numbers are the primary cross-references; the same 35mm ATE rear caliper was also fitted to a wide range of Mercedes-Benz and Volvo platforms of the same era.

How do I confirm fitment if there are multiple variants?
Use VIN, engine code, and chassis/platform details and compare them to the fitment section above. If unsure, request fitment assistance before ordering.
