Description
The ATE Master Brake Cylinder with reservoir is a vital component designed specifically for PSA Citroën and Peugeot vehicles, including models such as the Citroën C4 Picasso, DS5, as well as the Peugeot 3008 and 5008. This part plays a crucial role in the vehicle’s braking system by converting the force applied to the brake pedal into hydraulic pressure that activates the brakes at each wheel.
Over time, master brake cylinders may experience wear or leaks, leading to reduced braking efficiency or a spongy brake pedal. Replacing the master cylinder is essential to maintain optimal braking safety and performance. The installation process involves draining the brake fluid, removing the old cylinder attached to the brake booster, and carefully fitting the new unit before refilling and bleeding the brake system to remove air.
Regular inspection of brake components is recommended, as master cylinder failure can be caused by wear of internal seals, corrosion, or contamination of brake fluid. Ensuring the master cylinder is in good condition helps prevent brake system malfunctions and guarantees reliable stopping power.
