basically, not all 4 of my brakes are working. I've dealt with this problem since I've had the truck almost. but now is enough. when I brake it feels like I'm falling forward. when I compare it to my pops 07 it brakes nice and even. I've also got a lot of play in the brake. when I push it, it kinda sounds like your pushing air out of something. so I figure I have a leak in the abs system or maybe master cylinder? but how would I check this? and hopefully fix it? my front pads are always worn a ton more than the rears. and my slotted rotors all around didn't help much. any help at all is appreciated

 

Sounds like you do have a leak somewhere. I would start at the master cylinder and trace all the hoses. There should be no brake fluid anywhere on any of the hoses. Make sure you check the calipers also, you could have blown out a seal inside a piston. It is completely not safe to continue to drive if you do have a leak. You're front pads should always be worn more than the back, since you do I would say approximately 70% of your braking with the front brakes. Make sure you check that all the bleeder screws are tight also. Give that a shot. You should have NO brake fluid on any hose, line, etc. period. It's a closed system.

 

yeah, no fluid leaks at all. since I've had the truck, no leaks period. fluid anyway. I've had brakes done at brake shops and I've done em myself. still no change and I havent asked, always forgot about it. only 1 time did I have the tight brake feeling. I think first time I had brakes done in 05 or so. when I pressed on pedal there wasnt any play. but since then its just gotten to the point where its play first then brake

 

Maybe you should try bleeding the brakes. See if there's still air in the line. Maybe see if you have a vacuum leak on the brake booster. Possibly a bad brake booster or a master cylinder taking a crap on ya? I would start with bleeding of the brakes if the fluid level in the master cylinder hasn't moved/gone down.

 

so if bleeding didn't work, how else can I test the brake system to try and pin point the problem?

 

Also check to see if there's a leak in the vacuum system for the booster. Are you losing any fluid in the reservoir?

 

sounds like you may have a bad caliper somewhere on the truck. One of 'em isn't functioning right if everything checks out. Either that or the proportioning valve.

 

no fluid leakage at all. just the squishy pedal

 

Start by jacking up each side of the truck and see if while you spin the tire and someone hits the brakes if the tire keeps spinning. Or spins longer than it really should. Did you bleed the brakes? If you did, how did you do it and what part of the truck did you start with? front/left, right/rear?
