Hello so I have a 2002 gmc sierra 1500hd 6.0
I only replaced the hydroboost due to the inside push rod leaking so I decided might as will do a hydroboost upgrade like I seen on YouTube so I got an 11 HB installed it and bleeded the system and refreshed the fluid and on frist Initial test it was like night and day different the pedal feel great but when
I backed up and turned wheel it was applying breaks and the more I turn the wheel the more it applied the brakes I was like WTH
So I decided to just go for a test drive and omg you can feel that the truck was being held back and the harder you push it it was not going to go any faster and as I turn the wheel you can see the pedal being apply by it's self
So I took the master cylinder off and did a test and i turn left or right you can see the push rood being push out
So I put my old one back in and re-did the procedure and everything went back to normal so I wanted to know 11 HB I got is it bad or it just does not work for my truck
