I need to replace my brake booster and looked over the information cliffyk sent me and it seems pretty straight forward. My local shop wants to bang me for close to $600 to do the whole job. Has anyone does this on their own and if so how hard was it? Any insight would be great. The only issue I see would be bleeding the brakes after.

 

It's easy enough. You may not even need to disconnect the brake lines if you can detach the master and move it away far enough to remove the booster.

Remove the pushrod from the pedal first, remove the master, then remove the booster. Wiggle room is the trick.
