Internal hose degradation and environmental exposure are among the leading causes of pressure loss, uneven caliper response, and fluid leaks in fleet brake systems. Over time, rubber lines develop cracks, dry rot, and internal collapse, which can cause spongy pedal feel, delayed brake engagement, and potential safety hazards. Upgrading to this premium OE replacement caliper ensures a robust, sealed hydraulic pathway that restores immediate response and prevents volumetric expansion during severe-duty stops.
This caliper features a high-quality silver zinc coating for corrosion resistance and long service life. Designed specifically for heavy-duty fleet applications, it seamlessly replaces original equipment with a direct fit for the rear right position on Mercedes-Benz SLK280, SLK300, SLK350, and various C-Class models from 2000 to 2003. Its structural integrity supports consistent pad engagement and caliper stability under demanding operational conditions, making it ideal for commercial vehicle and industrial fleet use.

Expert Installation & Field Note
Proper routing of this caliper is critical for optimal performance. Ensure hoses are routed to avoid chassis chaffing and allow full twist clearance during steering cycles. Check the mounting brackets on heavy commercial frames for secure attachment to prevent undue stress on the line. Our shop experience specializing in heavy-duty brakes since 1985 emphasizes the importance of verifying line length and fitting threads before installation, especially given variations in wheelbase and production runs that can affect routing and fitment.
Before ordering, physically inspect your existing brake line length, banjos, and flare fitting threads. Fleet and utility vehicles often have mid-year production changes and wheelbase variations that alter line routing. Confirm compatibility to ensure proper fit and function.
