Would you put the bigger brake shoe on the front or the back of the back brakes for a 1994 Pontiac grand am?
the big/longer shoe generally(99%) goes to the back.(check mnufacturers specs) try www.autozone.com
Why would you lose pressure in your brake pad after changing the back brakes on a 1992 Pontiac Grand Prix?
You would push down on both the front brake and the back brake. You would want to put a little more pressure on the back brake and slowly add pressure to the front brake. If you slam on the front brakes there is a possibility that you will fly over the handle bars. I know from experience and it is not fun. I hope this helped.
you never want to completly empty your resevoir. air bubbles will get in your brake lines and will make it super hard to stop. you should just add fluid. if you really do want to change it all out then you need to disconnect the brake line at one or all the tires and pump the brakes until its all out. but when you go to put more in then you will need to bleed…
