Sorry for late response .. I m not any one of the above discussed but actually I had to go somewhere after I posted .. The solution which I applied on my corolla Xilinx 2003 was to replace the hydraulic braking oil distribution kit nearby and now it's almost like not skidding anymore ..
What's the main problem : u can all check this out in ur vehicles
Try to apply ur brakes by placing someone outside and ask him to c what happen when u apply the brakes ... The pressure ratio for the front and back wheels is 60/40 which makes the front wheels stop atonce while back wheels continue moving resulting in skidding of car even at slower speeds..
After changing the kit now the pressure applied Is evenly distributed for all the four tyres and car has a firm road grip.
Anyone living in pindi Islamabad can contact me and come to me and have a comparison .. I just wanted to help all ov u being so frustrated about this problem.
