Will this Power Brake Booster fit Chevrolet Silverado 1500 ?

Yes, it fits Chevrolet/GMC. Specific models can be viewed at five points.

How can I test my hydraulic booster?

A hydraulic booster can be tested just like a vacuum booster. With the engine off, pump the brake pedal until you feel firm resistance, then hold. Start the engine. Proper operation should result in the brake pedal slightly sinking.

Will I need to retain my master cylinder pushrod?

Yes, the master cylinder pushrod, spring and retainer will need to be retained and reused on the replacement hydraulic booster.

Will I need to bleed my power steering system after installation?

Yes, since the power steering lines have been removed, the system has been subjected to air. The power steering system will need to be bled using the O.E. bleeding procedure.

What type of fluid does a hydraulic booster require?

As part of the power steering system, hydraulic boosters require O.E. power steering fluid.

Good deal as long as you can use old pushrod, spring, and retainer

Good price for the item my biggest complaint was the fact it didn’t come with the pushrod, spring, and retainer. Had to reuse them from the old booster and I’m not a fan of that.
