Soft brake pedal? (Intermittent)

[98 Exceller]

I have a soft brake pedal on our 1998 Excel. When I put my foot on the brakes, I have to push down harder and harder to get it to stop quickly, and I can feel the pedal sinking lower and lower as I keep pressure on it when I have finally stopped. Would this be the master cylinder? I have bought a new one and am going to fit it tomorrow. It cant be the booster can it?

thry doing what i told stickshift to do in the other post


Did you properly adjust the rear brakes using the adjuster. Jack the back end off the ground. remove the drums and turn the adjuster. put the drums back on and soin the sheel to make sure you did not over adjust them.

When properly adjusted the wheel when spun should have hardly any friction. the best way is to adjust them so there is friction and then slowly adjust them down till the friction is gone.

the rear brakes are supposed to be self-adjusting but never works.

Yeah, I already adjusted the rear brakes and I know how they are supposed to adjust but they dont, so that is all ok. I also have brand new pads in the front.
