alrite well to start its a 1997 Chevy K1500 Z71, 350 vortec, 4l80 trans swap, 4x4, 6' RCX lift on 35s.
well i bought it with a bad wheel cylinder thus my pedal going to the floor, he had been driving it like that for some time, i had to drive it to work for a week before fixing it.
SO today, iv replaced both wheel cylinder, shoes hardware, in back, up front i checked the calipers, all is well they look new within the past year, i did brake pads (i bought ceramic) and replaced the rotors..
we bled the back brakes twice, few times each wheel, and the front brakes, starting with the RR first ending with the LF,
now, when i bought it soft pedal engine running or not due to blown wheel cylinder and empty reservior, NOW i have a very firm and strong pedal that does NOT drop when holding it down with the engine off, it is about 2/3 the way up and hard, if u hold the brakes and start it the pedal goes almost to the floor
i did get fluid at all 4 brakes, the truck does stop just not well, no pulling or anything
on gravel, the back breaks lock up as they should not to easily, the front breaks dont lock up that easy, on the highway both sides DO get HOT and you can smell them but the truck doesnt stop quickly due to very soft pedal...
now iv tried googling this and learned alot but have NOT found a definitive answere
iv gotten
bad mastery cyl (im doubting this because it hold pressure when engine off and all 4 wheels have braking action)
iv seen maybe i dont have the back breaks adjusted right (in the AM i will pull the drums have them cut and adjust the brakes up tightly)
iv seen crappy rubber brake hoses are expanding (im puttin new ones on in the am and getting a new master cyl incase i have to replace it)
and LASTLY iv seen air in the abs module thing, which i know NOTHING about im old school never messed with trucks or cars that had abs till this truck.....
iv seen i need a scan tool to activate the motor and cycle the valves or have the abs kick in on gravel...
well after i repaired the brakes i also put the fuse in the abs spot which was removed due to the blown wheel cylinder. at first the abs would come on very easy especially when turning or backing up, then on gravel, now i can hit the brakes on gravel and the abs didnt come on, i tried this time in a parking lot that has basically a thin layer of debris and gravel all over it and no abs came on
also no brake or abs lights on the dash
IM AT A LOSS i need this to get to work, looking for ANY help towards what this could possibly be, thanks so much in advance all here at GMT400
** in the am im going to cut the drums and adjust, and bleed the holly hell out of it to see if that works but for some reason im unsure the ABS module thing where they say (that has to be cycled) or some crap is throwing me for a major loop
i apologize for such a long post i just wanted to get everything out there so we dont have one of those monotonous threads where it goes on on and asking questions about the truck and what i already did to fix the issue,
