Thanks for the reply !! Iam pretty shure the brakes are adjusted right . I dont no what kind of power brake booster it is ? it all looks new, like it came in a kit. Is there any way to tell if its for drums or disks?? And no the brakes do not change with the engine running or off , and i pumped tell my leg fell off both ways with little to no change. All the after market brake booster kits i have seen all have a proportioning valve right under the master cylinder but not mine ! Dont know if it matters or not but this is a stock location set up , still under the floor .
