Hi I have a 2000 chevy blazer 2in suspenion lift, 2in body lift, and 31's the reason I'm posting this is as soon as I put all these things put on my brakes started going out. I have replaced all brake parts and the master brake. They go out whenever I cut the wheel all the way to either direction to were they don't turn anymore they go to the floor, but I can pump them back up. I have now found any pinching or over exstention.

 

seen this issue before after putting a 2inch lift on a blazer for a customer at work. what was happening is those stupid new upper control arms are were actually hitting the caliper or caliper bracket (this was like 8 months ago so im trying to remember) thus pushing the caliper piston back into the caliper causing the pedal to go the the floor. so check that. turn the wheel all the way one way and lay under it with the truck on the ground and see if your calipers are hitting anything under full turn.

basically what we did was grind down the control arm a hair to stop the caliper from hitting. i have pictures of it somewhere, if i can find them ill post them

 

found them. yeah the upper control arm was hitting the caliper pin causing the caliper to push in.




so just ground down that corner on both sides and took care of that

 

cant believe i have been driving a year with them doin this, i pretty much gave up hope but i just got back on here. thank you so much ima go try this!

 

and this will not cause any structural damage to the control arms?

 

Do your brake hoses also look all chewed up? I'm having the same problem but my brake driver side hose is all chewed up I'm thinking something is on pinching it think steel brake hoses will fix the prob? Anyone ever do this? Anyone recommend good inexpensive ones?

 

Make sure to check your regular components as well. Master/slave cylinder, brake fluid and hoses.

Although it's probably lift related, it could have just been coincidence, as well.
