4.8X5 was mentioning me on this situation…

what happen to mine was
i was on the highway, driving normal around 80-90mph….
cuisine then i try to slow down as a vehicle went in front of me suddenly and from that point the pedal felt funny( pedal was stiff to a point of not moving) and the car suddenly start to slow down like the caliper was "stuck" so i quickly went on shoulder taking 3 lanes to move and after i stop completely turn of the car waited for like 5 mins hoping the X would go on "reset mode" then i started her up, put her on D and the car is Stuck,stopped,seized IT WAS NOT MOVING…so i forcely drove it exiting the highway for about 1mile stop on gas station and called Tow Truck….put her at the shop, first was Brake Module, which was under the steering wheel,..

next day,
drove her to highway and BOOM!…brake seized AGAIN…drove her back now all 4's are smoking, dropped her off again,
Now, Brake Booster is Going, Replaced,
MC Replaced also, suggested bleed the lines,…at this point This acted up on Monday, and MPACT is Saturday….with all these process of elimination i don't have time for it so i gave them the GO word to just change the whole brake system,

they ended up bleeding the lines 7 times as everything was changed except the calipers(which was fine) they said that the lines was causing some soft force when you press on brake pedal to a point it was going almost to the floorboard 7x later it was back to normal …shop called me Friday night, left keys and took it to Mpact M.D. a 4hr drive…..


first suggest to bleed the lines, check MC, then Brake Booster and Fluids
