Product Description
Product Function Description
The wheel brake cylinder is a critical component of your ISUZU D-Max‘s rear drum brake system. This hydraulic device converts the pressure of brake fluid into mechanical movement of the brake shoes. When the brake pedal is pressed, hydraulic fluid is forced into the brake cylinder, causing the pistons on either side to expand outward, which presses the brake shoes against the brake drum to slow the vehicle . For the ISUZU D-Max I and II, a properly functioning wheel cylinder ensures consistent braking performance, reliable stopping power, and safe vehicle operation.
Product Specifications
Why Choose This Wheel Brake Cylinder?
Restores Braking Performance – A leaking or seized wheel cylinder reduces braking effectiveness. This new cylinder restores proper hydraulic pressure and smooth shoe movement for reliable stopping power.
Direct Replacement – Precision-engineered to match the original cylinder specifications. Direct bolt-on replacement – no modifications required.
Prevents Brake System Damage – A failed wheel cylinder can leak brake fluid, contaminating brake shoes and damaging the brake drum. Replacing it early helps prevent more costly repairs.
Proven Compatibility – This cylinder is confirmed compatible with ISUZU D-Max I and II across multiple years, engine variants, and chassis codes including TFR and TFS .
Quality Construction – Manufactured with an aluminium body and precision components to withstand demanding conditions and provide long service life .
Features & Functional Notes

Brake fluid leakage from the cylinder indicates seal failure and requires immediate replacement .
-
Regular inspection of the brake system is recommended for safe vehicle operation.
Package Contents
1 x Wheel Brake Cylinder. Note: Brake shoes, brake fluid, and mounting hardware are NOT included unless stated. Please confirm compatibility with your ISUZU D-Max model, year, and chassis code before purchasing. It is recommended to replace wheel cylinders on both sides together for balanced braking performance.
Installation Tips
Important: The brake system is a critical safety system. Professional installation is strongly recommended. Safely raise the vehicle and support it on jack stands. Remove the rear wheel and brake drum. Clean the brake assembly area thoroughly. Disconnect the brake line from the old wheel cylinder . Remove the mounting bolts and take out the old cylinder. Clean the mounting surface on the brake backing plate. Install the new wheel cylinder and tighten the mounting bolts to factory torque specifications. Reconnect the brake line. Install new brake shoes if needed. Reinstall the brake drum and adjust the brake shoe clearance. Bleed the brake system (starting from the wheel farthest from the master cylinder) to remove all air. Critical Step: After installation, test the brake pedal – it should feel firm. Check for fluid leaks around the new cylinder connections. Test the brakes at low speed to ensure proper stopping and no pulling. Professional installation is highly recommended.
FAQ
Q1: How can I be sure this wheel cylinder fits my D-Max?
A1: The most reliable method is to check the existing part number on your vehicle's rear wheel cylinder. This part is confirmed for D-Max I and D-Max II with rear drum brakes. Always verify via VIN.
Q2: Is this for the left or right side?
A2: This wheel cylinder fits both the left and right rear sides of the D-Max .
Q3: What is the piston diameter?
A3: The piston diameter is 23.81 mm (approx. 23.8 mm) .
