Welcome to the world of SUPPOSEDLY bolt on after market products brother :sign0020:
I feel your pain my friend, 1 year later i just about have everything taken care of, or working properly on my supposedly bolt on 2" drop spindles kit with disc brakes and a 8" dual brake booster & master cylinder kit from Performance On Line. The last problem I have had is the booster is faulty (they have sent me a second one with the same exact problem) and does not return the brake pedal the last half of a inch to turn off the brake light switch. So after a year of going round & round with P.O.L. , i finally just installed a in line pressure switch on the brake line to turn on & off my brake lights. I will run the booster until it finally takes a crap, and then i will use it for target practice for my 357 and buy a new one from a better manufacture like CPP or Heits.
Needles to say i have also replaced the Chinese version of wheel bearings, races & brake pads on 57 within the first 500 hundred miles with the P.O.L. kit
If you get bored, here is some reading material for ya, and you can see the frustrations i have gone threw also, trust me when i say you are not the only having issues with the supposedly bolt on after market world.. :sign0020:
