The Valeo 21-52-6-775-924 is a premium hydraulic clutch slave cylinder designed for BMW vehicles with manual transmissions. This component is mounted on the exterior of the transmission bellhousing and works in conjunction with the clutch fork to actuate the release bearing, enabling smooth clutch engagement and disengagement.

Key Features:

• Manufactured by Valeo to OEM specifications for precise fit and reliable performance
• Equipped with automatic adjustment to compensate for clutch wear over time
• High-quality construction using premium materials for exceptional precision and durability
• Multi-point quality tested for guaranteed endurance and performance
• Includes protective dust caps to prevent contamination
• Direct replacement for BMW part numbers 21521158903 and 21526766277

Common Failure Symptoms:

• Clutch pedal goes to the floor without resistance
• Brake fluid leaking near the transmission bellhousing
• Difficulty shifting gears or incomplete clutch disengagement
• Spongy or soft clutch pedal feel

The hydraulic clutch system uses brake fluid to transfer force from the clutch pedal to the release mechanism. Over time, the corrosive nature of hydraulic fluid can degrade internal seals, leading to leaks and system failure. Replacing a failing clutch slave cylinder restores proper clutch operation and prevents damage to other transmission components. This part requires bleeding of the hydraulic system after installation to remove air and ensure proper function.
