Vacuum Brake Booster Oil Seal — ATE 03.7718-5028.1 | Universal
Stop Brake Booster Oil Contamination — Direct Replacement ATE Oil Seal.
A failed vacuum brake booster shaft oil seal allows engine oil to enter the brake booster vacuum circuit — causing a "stiff" brake pedal, degraded brake feel, and internal booster damage. This ATE replacement seal restores a leak-free booster shaft seal and protects the booster from oil contamination.
Why Replace This Seal
- Stops Oil Contamination: Seals the booster shaft against oil ingress from the vacuum pump.
- Restores Brake Feel: Prevents booster diaphragm oil damage — maintaining correct servo-assisted braking.
- OEM-Quality Supplier: ATE is a Tier 1 brake systems supplier to major European manufacturers.
