## Questions & Answers

**Q: Will this Power Brake Booster fit Chevrolet Silverado 1500 ?**
A: Yes, it fits Chevrolet/GMC. Specific models can be viewed at five points.

**Q: How can I test my hydraulic booster?**
A: 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.

**Q: Will I need to retain my master cylinder pushrod?**
A: Yes, the master cylinder pushrod, spring and retainer will need to be retained and reused on the replacement hydraulic booster.

**Q: Will I need to bleed my power steering system after installation?**
A: 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.

**Q: What type of fluid does a hydraulic booster require?**
A: As part of the power steering system, hydraulic boosters require O.E. power steering fluid.
