Heavy-Duty Truck Brake Caliper Assembly – Premium Replacement by mikes auto parts
1. Product Overview
When it comes to maintaining the safety and performance of commercial fleets, the braking system is non-negotiable. Our Heavy-Duty Truck Brake Caliper Assembly is engineered to meet the rigorous demands of Class 8 trucks, trailers, and vocational vehicles. Sourced directly from mikes auto parts, this caliper delivers OEM-grade stopping power, corrosion resistance, and long service life. Whether you are a fleet manager or an independent mechanic, this component ensures your vehicles remain compliant with DOT safety standards while reducing downtime.
Each unit is precision-machined from high-strength cast iron and undergoes a 100% pressure test before shipment. Unlike generic aftermarket options, this caliper includes pre-installed stainless steel guide pins and high-temperature rubber boots, eliminating the need for additional hardware purchases.
2. Key Features

7. FAQ
Q: Is this caliper a direct replacement for OEM part number 899150?
Yes. This assembly is designed as a direct cross-reference for Meritor WABCO 899150, 899151, and Bendix 5028000. No adapter brackets or modifications are needed.
Q: Do I need to bleed the brakes after installation?
Yes. While the caliper comes pre-bled, the system must be bled after installation to remove air introduced during line connection. We recommend a two-man bleed procedure for air disc brakes.
Q: Can I use this on a trailer with automatic slack adjusters?
Absolutely. This caliper is compatible with both manual and automatic slack adjusters. However, ensure the adjuster stroke is set to 1.25” before operation.
Q: What is the warranty process if I receive a defective unit?
Contact mikes auto parts customer service with your order number and a photo of the defect. We ship a replacement within 24 hours and provide a prepaid return label for the defective unit.
Q: Do you offer a left-hand and right-hand version?
This listing is for the right-hand (passenger side) caliper. The left-hand (driver side) version is available as a separate SKU. Both are identical internally but mirror-mounted.
Note: All specifications are subject to change based on production batch. For exact fitment verification, please provide your VIN or OEM part number to our support team.
