Hi there! If you are looking for the sizes, I believe the four nuts behind the dash are 14mm. The brake lines off the master cylinder are 10mm.The bolts that hold the master to the booster are 12mm.You have to get under the dash and unhook the four nuts and the brake pedal.When you reinstall the master cylinder,make sure you do not change the length of the push rod.Her is some more info.Hope it helps!Thanks
Disconnect the vacuum hose from the booster.
Disconnect the brake lines from the master cylinder.
Remove the brake pedal-to-booster link pin and the booster-to-fire wall nuts. The pushrod and nuts are located inside the vehicle on the driver's side, under the dash.
Remove the booster with the master cylinder attached.
Install the booster in position and tighten the mounting nuts to 9 ft. lbs. (13 Nm).
Connect the vacuum hose to the booster and the fluid lines to the master cylinder. Tighten the fluid lines to 14 ft. lbs. (19 Nm).
Bleed the brake system.
