Here is my dilemma. I hit the brakes and they pulsate / jerk real bad. I have bleed them twice. Pad's look good. Only thing I'm starting to think is the master cylinder. Let me know if anyone can come up with another idea.... Thanks

 

The pulsation, do you feel it in the pedal, or in the steering wheel? If you feel it in the pedal, your drums might be warped, if in the wheel, your rotors might be warped. Check that, as it is likely your least expensive way to go. As for the jerking, is it the same direction each time? How does the vehicle drive when not braking, straight line, or does it veer off to one side? Loose/warn suspension parts can lead to a hard pull while braking. Also, if you have a stuck caliper or other braking components, that can cause the pull as well.

 

+1 check your rotors, when my dads warped the pedal pulsed so bad it almost threw your foot of it

 

95% of the time it is the rotors. The brakes are kinda small on our rigs so this is a large problem.

I did do a post on this if it is a continued problem. Here is a link if it continues brakes!!!

I really like the new pads I installed. I have tried many pads and so far I like the Duralast Gold series.

 

It's mostly the pedal, but the steering wheel does shake as well.

 

One word "Rotors"

Time to have them ground or replaced.

 

sounds like drums and rotors are dure for some work. While the truck is up they can check into your pull issue, which may or may not be brake related.
