front brakes
i had to replace the front rotors, pads, and the passenger side caliper..i did all this and i bled the brakes if im driving it.. i have to pump it fully stroke about 4 times to get any braking power...i tried bleeding it some more and nothing...could the line for the back brakes being cut cause any kind of problems for the fronts? b4 i replaced the fronts it work with the back brakes being cut...it just takes about half pedal to engage the front and now it doesnt even engage until about 4 pumps....i dont get it im out of ideas...please help.

The front and rear are seperated in your master cylinder,BUT,you need to get the rear repaired,or dont't drive it,on these trucks, about 80% of the stopping is done with the front,and naturally,about 20% on the rear,but that is no reason to be driving around with no rear brakes,also,if you think you have bled the sysyem AFTER you repair the rear,which by the way,will cost alot less than someone's life,you may want to take a look at replacing the master cylinder,and bleeding the system some more,ONLY after the back is repaired.If you are not sure what you are doing,by all means,get it to a repair shop.

Try this: disconnect one of the lines from the wheel cylinder. Now step on the brake pedal. What happens?

You have got to be kidding...right?

This guy needs to get his truck to a shop and his head examined while he's at it. That is, if he's not dead already.

Andy,Yes it will go to the floor,but in the master cylinder,how many lines do you have comming out of it,The rear section of the master cyl is for the front brakes,the front section is for the rear brakes,I,m not trying to make you or anyone else on here mad or try to get into a pissing contest with anyone,but this is one thing i know about,I have worked on MANY vehicles in my day,and I know how a hydraulic brake system works very well.But yes you are right,it will go to the floor,also you are right about another thing,he needs to get it to someone that knows what they are doing,or park the truck.Also he did say the lines are pinched off for the rear,meaning no fluid is going to the rear at all.unless it is not pinched off tight enough,then he is losing fluid there.

Ok, I understand where you're coming from. And yes, I understand that there are two lines coming out of the master cylinder. So I've never understood why if there are two separate lines the pedal will go to the floor without rear brakes. Maybe you can explain that to me - again, not being a wiseass, I just don't understand it myself.

It basically follows the path with least resistance,with an open line,the fluid will go into that line alot faster than a closed line.although there are 2 seperate sections to a master cyl,the fluid will still follow the path easiest to travel,also,alot of master cyl's have 4 lines comming out of them,one for each corner of the vehicle,and vehicles will have a proportioning valve in-line after the master cyl, that if operating right,will regulate the pressure going to the corners.

Well,just like I said,as long as you have the line pinched off good,no fluid will get out,and they will work,but you still need to see about getting them repaired,they are put on there for a reason.In an emergency situation,its not going to be good,especially if you get in a crash,and the insurance co.finds out you had no rear brakes.But anyways,what did you do get it repaired?Just curious.
