I have a 2001 f250 short bed ext.cab 4X4 with 4in lift and 315/75/16 tires, it has around 77k miles on it. I test vehicles for a living and I can say that it takes some bad breaks to scare me, and mine scare me once in a while. If someone decides to turn at the last minute then I am ready to wet myself depending on how close I am to them, and I try to keep my distance. This is at any speeds over 10 mph at 10mph If I try hard I can get wheel lock. Here is the worst part, When applies at a normal speed (not panic apply) the brakes seem to do OK. At a panic apply the pedal seems to drop further than normal and the brakes seem to do let the harder I press them. I am ready to buy $1200 SSBC from calipers but I am not sure if even that will fix it because I am not sure if that my problem. Do you think the problem is in the friction material or in the hydraulic system? Any ideas would be great, and Yes I know it’s a big truck with big tires but it’s bad when you’re going 25-35 mph, 2 car lengths behind someone and you can’t stop for anything. … Thanks.
