Mercedes Sprinter Left Rear Brake Caliper – Brembo | VS30 1500 / 2500 | #9074233100 (2019–2025)

A seized or leaking left rear brake caliper on a VS30 Sprinter 1500 or 2500 causes uneven braking, premature pad and rotor wear on the left rear corner, and — if the caliper sticks in the applied position — the dragging brakes, burning smell, and heat buildup that signal immediate service is needed. This is the Brembo rear left brake caliper for VS30 Sprinter 1500 and 2500 models with manually operated (non-electric) parking brake, a direct replacement that restores proper rear left clamping force and balanced braking across the rear axle.

What This Part Does

The rear brake caliper is a single-piston hydraulic clamping assembly that straddles the rear brake rotor and presses the brake pads against the rotor when braking force is applied. On the lighter-duty Sprinter 1500 and 2500 rear axle, the single-piston design is sized for the stopping loads of a single-rear-wheel configuration. When the caliper's piston seal degrades and allows fluid bypass, the piston sticks in the partially applied position, dragging the left rear pads against the rotor continuously. When the slider pins corrode, the caliper body loses its ability to float and only the outboard pad makes consistent contact — causing rapid, uneven wear that accelerates rotor damage on the affected corner.

Common Symptoms of a Failing Rear Brake Caliper

• Vehicle pulling toward the right under braking — left rear caliper dragging
• Left rear brake pads wearing faster than right rear
• Heat, burning smell, or smoke from the left rear wheel after driving
• Brake pedal pulsation when stopping, particularly at speed
• Brake fluid leaking from around the caliper body or bleeder valve
• Caliper piston or slider pins found seized during brake service inspection

When to Replace

Replace when the caliper is confirmed seized, leaking, or unable to retract properly after brake service. Always replace rear calipers in pairs — left and right — to maintain even braking balance. Replace brake pads and inspect rotors at the same time, and bleed the brake system after installation.

VS30 1500 / 2500 Specific — VIN Verification Required

This is the rear left caliper for VS30 Sprinter 1500 and 2500 models without electric park brake. It is not compatible with VS30 Sprinter 3500, 3500XD, or 4500 rear calipers, models equipped with an electric park brake, or NCV3 Sprinters. Always verify by VIN before ordering.
