please help.. PLEASE.. my front brakes are locking up.. I cabbages everything possible,.. brake booster, master cylinder, brake pressure switch front calipers , hoses.. it's still happening.. can anyone please help??? PLEASE..

 

Cabbages? Any warning lights (abs)? If you have changed all these parts and problem still exists; IMO you need a professional to look at it. If something other than DOT 3 brake fluid was used that could be cause.

 

I think he put in dot 4.. so can i bleed the brakes or flush then and put in dot 3?

 

Most DOT4 is compatible with DOT3, DOT5 is not. I still think you need a qualified person to look at it and advise you of what to do. IDK if flushing fluid will help anything. ABS should keep brakes from locking. If rear brakes aren't working that could cause front brakes to lock up.

 

rear brakes are working.. I took it to the dealer and they said the car is too old and too many miles to fix.. they declined to work on it.. 2007 140k miles..

 

I had heard of dealers turning away work, I don't understand it. I would try another dealer, try a Chevy or GMC. Has you Escalade been modified or is it all stock?
