Q: How to replace the Vacuum Brake Booster (ABS) on Chevrolet Malibu?
A: Begin the vacuum Brake Booster replacement task by securing power off the vehicle to defend from ebcm/ebtcm malfunction. Supported under the vehicle position your left front wheel assembly to access its installation point. Use a socket to remove 3 wireless ebcm/bpmv bracket nuts on the left front wheelhouse and lower the entire automobile.

Insert bleeder valve caps into each of the 4 brake pipes at the bpmv to stop fluid loss while maintenance. Remove the vacuum Brake Booster master cylinder nuts then detach the ebcm/bpmv bracket assembly together with the brake master cylinder.

To free the pushrod from the Brake Pedal pin remove the connection parts including the pushrod retaining clip , wave washers and booster pushrod while tilting the booster to separate the parts without forceful side pressure. Take out the booster unit from the vehicle. Return the booster to its position and tilt the unit to match the pushrod with the Brake Pedal pin while installing without pressing too hard. Thread the Brake Booster pushrod retaining clip, wave washers, and Brake Pedal pushrod connections back to the Brake Pedal pin. Install the 2 Brake Pedal assembly to cowl mounting nuts but tighten them to 15 nm (11 ft. Lbs.). Put back the electrical brake apply sensor connector before mounting the master cylinder gasket side with the jp1 and ebcm/bpmv bracket. Fasten the master cylinder screws to the vacuum Brake Booster securing unit with 25 nm (18 foot lbs.) torque. Continuing with the vehicle raised put on the 3 bracket assembly ebcm/bpmv nuts to the left wheelhouse, snug down to 10 nm (86 inch lbs.) before reattaching the wheel and tire apparatus left front. Seal-free brake pipe ends and match up the 4 connections to the bpmv unit. Tighten each connection to 20 nm (15 ft. Lbs).

Q: How to replace the hydraulic brake booster on Chevrolet Tahoe?
A: Wheels must be blocked while applying the park brake as the first step for hydraulic Brake Booster replacement. The installation requires users to detach the inlet hose plus steering gear while releasing the booster assembly hoses and extracting the master cylinder along with the stop lamp switch. You must remove the 4 booster to bulkhead nuts before taking out the booster assembly and its gasket. Place the gasket and then install the booster assembly according to the fastener notice in service precautions. The 4 booster to bulkhead nuts require tightening to 36 nm (26 ft. Lbs.) while the stop lamp switch and master cylinder need to be installed. The final steps include reattaching return hoses together with steering gear before bleed the hydraulic booster and finally free up wheels through releasing the park brake.
