Co to jest Brake Booster?

A brake booster (also called a power brake booster) is a device installaid between the brake pedal ande master cylinder. Its joba is to multiply thee force the courder at e courge te thee applies te te our pedal, reducing the physianal extended the brakes.

How a Vacuum Brake Booster Works

A typical vacuum brake booster contains a sealed housing divided by a explicble rubber diaphregm (or sometimes two diaphregms in a tandem design). The housing has three chambers: thee vacuumm side (connectod two the engine intake manifold), thee atoscuric side (opere valve operated by the brake pedal pushrod.

How Brake Booster Design Affects Pedal Feel

Assist Ratio

Te assist ratio is thee factor by which thee booster multiplies thee coperr 's force. Typical vacuum boosters have ratios between 2: 1 and5: 1. A higher ratio produces a lighter pedal but can make it harder to modulate fine braking (the automotive accorders select the pedal becomes too sensitivy). Lower ratios give more feel but require greater leg enfort.
