New master cylinder, new wheel cylinders and brake pads.I bled them and have a good pedal if I do not release the brake pedal all the way. If I release it the pedal all the way the next time I hit the pedal it is hard to push.

Hi,

Replacing the booster isn't too hard. You will have to remove the brake master cylinder to access it. The worst part of the job is unbolting it from the firewall, It is one from the inside of the vehicle up under the dash.

If you look at the attachments below, I included the directions and the pics specific to your vehicle for replacement.

I hope this helps. Let me know if you have other questions.

Take care,

Joe
