Sorry it took so long to get back and answer. I changed out the front calipers and new brakes, one because while doing a tune up and brake job one of the front pistons in the caliper was stuck. So replaced both front calipers and brake pads.....great brakes now. Now to do the back ones.

 

thanks for the feedback on the stuck caliper.will check out my van

 

Yeah evidently the brake calipers pistons where bypassing or semi stuck. replaced both front ones with reman's and have all kinds of brakes. That and finding out how to bleed the calipers/brake system the right way.

 

And update.
Replaced all calipers, brakes, and rotors turned. bled all the lines and replaced master cylinder. The manual said to leave the bleeder valves open for about 20 or so pumps each and then tighten them. Have great brakes better than it has ever had.
Thanks for everyone's help.
