2001 speedster 2.2 - i recently had a small crash (only front clam damage). I was diving in 80 kn/h and the car ahead suddenly slammed the brakes, so i did to just to realize i only had about 50% of the brake power, i realesed and slammed the brakes again with no results, i hit the car infront at like 15 km/h. the car is now in a workshop getting the repairs done and the insurence covers it all but im still stuck with the brake problem. ive read myself to know that the problem could be the original 2 channel abs system that went into whats called ''ice mode'' or that the master brake cylinder has broken somehow.
question 1: any thoughs/exepriences of what coould have went wrong and coused the brakes to not work properly?
question 2: experiences/recommendations on removing the original abs system or uppgrading to a 4 channel abs system?
question 3: upgrading to a 4 pot front brake kit, is it worth it? link to the kit you recommend!
