To determine whether your car has hydroboost or vacuum boost, consult the owner’s manual. The owner’s manual will specify which of the two technologies your automobile employs. If you do not have access to the owner’s handbook, there are several additional ways to determine this information.
First, consider the sort of brake pedal installed in your car. Hydroboost systems employ a brake pedal that is more rigid and requires more force to depress. Vacuum boost systems feature a brake pedal that is softer and easier to depress.
The second step is to examine the brake booster itself. The brake booster is a cylindrical component often positioned near the engine compartment firewall. Hydroboost systems employ a larger, typically metallic booster, whereas vacuum boost systems use a smaller, typically plastic booster.
The final step is to examine the power steering system. Hydroboost systems utilize an independent power steering pump, whereas vacuum boost systems use the engine’s suction to power the power steering system.
If you’re still uncertain about your vehicle’s boost system, you can always have it inspected by a professional. They will be able to identify your vehicle’s system type with certainty.
