  Q: How to remove and install a power brake booster unit for the Honda Accord?

  A: Depress the brake pedal several times with the engine off and make sure there is no change in the pedal reserve distance. Depress the pedal and start the engine. If the pedal goes down slightly, operation is normal. Start the engine and turn it off after one or two minutes. Depress the brake pedal several times slowly. If the pedal goes down farther the first time but gradually rises after the second or third depression, the booster is airtight. Depress the brake pedal while the engine is running, then stop the engine with the pedal depressed. If there is no change in the pedal reserve travel after holding the pedal for 30 seconds, the booster is airtight. Power brake booster units should not be disassembled. They require special tools not normally found in most automotive repair stations or shops. They are fairly complex and because of their critical relationship to brake performance it is best to replace a defective booster unit with a new or rebuilt one. To remove the booster, first remove the brake master cylinder. Remove the shock tower cross brace, if equipped. Disconnect the hose leading from the engine to the booster. Be careful not to damage the hose when removing it from the booster fitting. Remove and set aside the engine compartment fuse/relay box. Unclip the Brake Lines from the firewall. Remove the air filter housing. Working inside the vehicle, locate the pushrod clevis pin connecting the booster to the brake pedal. Remove the clevis pin retaining clip with pliers and pull out the pin. Remove the four nuts holding the brake booster to the firewall. Slide the booster straight out from the firewall until the studs clear the holes and pull the booster, brackets and gaskets from the engine compartment area. Installation procedures are the reverse of those for removal. Tighten the booster mounting nuts. Also, be sure to use a new cotter pin on the clevis pin. After the final installation of the master cylinder and brake hoses and lines, bleed the brakes.
