brake problem

Yes both sides were full and no brake light. One of the rotors had some weare on them. So i decided to replace calipers and rotors both.

When pushing down on brake to almost complete stop you could fell it jerk to the right and the pedal push back against your foot.

No after replacing the callipers then i bleed it. The pedal was still very low to the floor. I then replaced the master cylinder and i did bench bleed it. So it is still going to the floor. After all this now.No brake light has ever came on or the abs light either.

I have had the truck for 3 years and 60,000 miles no other problems have ever come up on it. When i bought it put new pads on front and rear with new rotors in rear. Nothing else besides that.The pedal going to the floor happened after i replaced the front callipers. That was the reason for replacing master cylinder.

Try gravity bleeding with both front caliper bleeders open, keep the master cyl full and let em drip for a while. The other aspect to your problem, did you start this because the pedal was low? If so check your rear brakes! They control pedal height, if they are not adjusted properly, pedal will be low!

no after replacing brakes had little peddal could pump them up. So then replaced master. After this and bench bleeding the master and gravity blkeeding and a pump to bleed with there is no pedal at all.

How was the pedal height before the brake job? If it was ok...look for the combination valve, have someone hold the needle at the end in while you bleed the front brakes, If that dosen't work get a power bleeder and bleed all four wheels in the proper sequence.

Ok dumb question time. What is the combination valve.
