Why Replace Your Reservoir?
Symptoms of a Faulty Part
- Visible brake fluid weeping or leaking around the master cylinder base grommets.
- Dashboard warning light indicating low brake fluid.
- A spongy, soft brake pedal caused by air being sucked into the hydraulic lines.
- Cracked or heavily discoloured plastic from years of engine heat cycles.
The Factory Original Advantage
- Superior Materials: Factory-original plastics withstand extreme engine bay heat without degrading or cracking prematurely.
- Exact Fit: Cheap aftermarket copies often leak at the mounting grommets within months. Original parts guarantee a perfect seal.
- Massive Savings: Save up to 70% by purchasing a quality, tested recycled part instead of paying inflated main dealer prices for a new unit.
Fitting Instructions & Required Tools
We always recommend professional installation, but for experienced home mechanics, the general procedure is as follows:
- Step 1: Use a fluid syringe to safely extract old brake fluid from the existing reservoir to prevent spillage.
- Step 2: Disconnect the electrical connector for the fluid level sensor.
- Step 3: Remove the retaining screw/pin holding the reservoir to the master cylinder housing.
- Step 4: Firmly rock and pull the reservoir upwards to release it from the rubber seating grommets.
- Step 5: Lubricate the new reservoir fittings with fresh DOT 4 fluid and press firmly into the master cylinder until seated flush.
- Step 6: Refill to the MAX line and perform a full brake bleed to remove any air from the system.
Required Tools: Fluid extraction syringe, T20 Torx / Flathead screwdriver, clean rags, DOT 4 brake fluid, and a brake bleeding kit.
