Technical Specification and Compatibility

A high-quality 15/904300 brake master cylinder by GX-AFTER. This is the key component of the braking system, responsible for generating hydraulic pressure when the brake pedal is pressed. It is designed for a wide range of JCB machines, including 4CX backhoe loaders, Telehandlers (e.g., 525-67, 530, 540), and Rough Terrain Forklifts (RTFL).

Features of the 15/904300 Brake Cylinder

Precise Pressure: Guarantees the generation of correct system pressure, essential for effective braking.
High-Quality Seals: Internal seals are resistant to brake fluid and prevent internal leaks (loss of pressure).
Durable Body: Solid body resistant to corrosion and cracking, ensuring a long service life.
Restores Braking: Essential for repairing the brake system, eliminating a "soft" or sinking brake pedal.

Application in machinery

Brand Type / Series / Model
JCB Backhoe Loaders: 4CX, 4C, 4CN
JCB Telehandlers (Loadall): 505, 525 (inc. 525-67), 527, 530, 535, 540
JCB Rough Terrain Forklifts (RTFL): 926, 930, 940

The list above is for reference. It is crucial to verify the part number 15/904300 on your old pump.

Related Parts and Hardware

When replacing the brake master cylinder, it is absolutely essential to replace the brake fluid and thoroughly bleed the entire system. We also recommend inspecting the brake lines (both rigid and flexible) and the wheel cylinders.

⚠️ Safety Warning

A failed master cylinder (e.g., internal leak) leads to a loss of pressure in the brake system. This results in the brake pedal sinking to the floor and a total loss of braking ability. This is one of the most dangerous failures and can lead to a serious accident and loss of machine control.

Part Role in the Machine and Failure Diagnostics

The 15/904300 brake master cylinder is the primary hydraulic cylinder in the brake system. It is mechanically linked to the brake pedal. Pressing the pedal moves a piston inside the cylinder, which compresses the brake fluid and sends it under high pressure to the wheel cylinders, causing the machine to brake.

  • › "Soft" brake pedal that sinks to the floor (sign of an internal leak, worn seals).
  • › Needing to "pump" the brake pedal to get a response.
  • › No brakes despite no visible external leaks.
  • › Visible brake fluid leak from the rear of the cylinder (at the booster or pushrod connection).
  • › Brakes locking on (cylinder not releasing pressure).

🔧 Expert Guide: Key Installation Tips

  1. New Brake Fluid: Never re-use old brake fluid. Always flush the system and refill with new, clean fluid of the correct specification (e.g., DOT4).
  2. Bleed the System: After replacing the cylinder, the entire brake system must be thoroughly bled, starting from the wheel furthest from the master cylinder.
  3. Bench Bleed: It is often necessary to "bench bleed" the new master cylinder before installing it.
  4. Cleanliness: Maintain absolute cleanliness. Any dirt or mineral oil (e.g., engine oil) in the brake system will destroy the seals.
  5. Check Booster: If the old cylinder leaked from the rear, check that brake fluid has not entered and damaged the brake booster.

Frequently Asked Questions (FAQ)

Does this cylinder fit a 3CX?

Use in a 3CX is possible but depends on the specific model and market. It is primarily listed for 4CX, Telehandlers, and RTFLs. Please verify the part number 15/904300 on your old part before buying.

My brake pedal feels "soft" and sinks. Is this the cause?

This is the most common symptom of a failed master cylinder (worn internal seals allowing pressure to bypass). Other possibilities are air in the system or an external leak (e.g., at a wheel cylinder).
