Mitsubishi Raider Drum Brake Wheel Cylinders

Mitsubishi Raider Drum brake wheel cylinders

Starting at $17.95, AutoBuffy stocks 1 drum brake wheel cylinders from Dynamic Friction. The wheel cylinder is the hydraulic actuator inside a drum brake assembly — it converts brake fluid pressure into mechanical force that pushes the brake shoes outward against the drum. A leaking or seized cylinder causes soft pedals, pulling, or complete brake failure on that corner.

Signs your Mitsubishi Raider needs a new drum brake wheel cylinder

  • Brake pedal feels soft, spongy, or sinks slowly toward the floor under steady pressure
  • Visible brake fluid weeping or pooled inside the drum, on the backing plate, or coating the brake shoes
  • Vehicle pulls noticeably to one side during braking, especially at low speeds
  • Rear brakes feel weak or ineffective even after shoes have been adjusted or recently replaced
  • Brake warning light illuminates due to fluid loss lowering the master cylinder reservoir level
  • Brake shoes are saturated with fluid and glazed, causing a grinding or scraping noise when stopping

Which drum brake wheel cylinder should you buy for your Mitsubishi Raider?

The most important factors are bore diameter, port location (inlet on left or right), and whether you need a single-acting or double-acting cylinder — these must match the original unit exactly or the pistons will not correctly actuate the shoes. Beyond fit, the main decision comes down to build quality and whether you want a direct OE replacement or an upgraded option with better corrosion resistance.

OE-Equivalent Replacement

Replacing a drum brake wheel cylinder on a Mitsubishi Raider

Remove the wheel, drum, and brake shoes to expose the backing plate, then disconnect the brake line and mounting bolts before pulling the old cylinder free — have a rag ready to catch residual fluid. Install the new cylinder, reconnect the brake line hand-tight before fully torquing to avoid cross-threading, reinstall fresh shoes and hardware, and reassemble the drum. Bleed the affected corner thoroughly before lowering the vehicle and testing pedal feel in a controlled area.

Frequently asked questions

How much does it cost to replace drum brake wheel cylinders on a Mitsubishi Raider?
Parts start at $17.95 per cylinder at AutoBuffy. Most vehicles need one or two cylinders per axle. Add shop labor of roughly one to two hours per axle if you are not doing the work yourself. Replacing brake shoes and bleeding the system at the same time keeps total labor cost down.
Can I replace just one wheel cylinder on my Mitsubishi Raider, or do I need to do both sides?
You can replace a single failed cylinder, but replacing both sides on the same axle at the same time is strongly recommended. Cylinders on the same axle share similar age and wear. Replacing only one often means the other fails shortly after, and mismatched hydraulic response can cause the vehicle to pull during braking.
Do I need to replace the brake shoes when I replace a wheel cylinder on my Mitsubishi Raider?
Yes, in almost every case. A leaking wheel cylinder saturates the brake shoes with hydraulic fluid, which permanently contaminates the friction material. Contaminated shoes cannot be cleaned effectively and will produce reduced stopping power and uneven braking. Install a fresh set of shoes along with the new cylinder to restore safe, balanced braking.
How long do drum brake wheel cylinders last on a Mitsubishi Raider?
Wheel cylinders typically last many years under normal conditions, but lifespan varies widely based on climate, brake fluid maintenance, and mileage. Road-salt exposure and old, moisture-laden brake fluid accelerate corrosion and rubber cup degradation. Inspecting the cylinders for seepage whenever brake drums are removed is the most reliable way to catch failure early.
Is it safe to drive my Mitsubishi Raider with a leaking wheel cylinder?
No. A leaking wheel cylinder should be treated as an immediate safety issue. Fluid loss reduces hydraulic pressure, causing a soft or low pedal. Fluid contaminating the brake shoes destroys stopping power on that corner. Continued driving risks progressive brake failure. Park the vehicle and have the cylinder replaced before driving again.
Do I need to bleed the brakes after replacing a wheel cylinder on my Mitsubishi Raider?
Yes, bleeding is required every time a brake hydraulic component is opened. Replacing a wheel cylinder introduces air into the brake line at that corner. The system must be bled — starting at the farthest wheel from the master cylinder and working inward — until only fluid with no air bubbles exits the bleed screw, restoring a firm pedal.
