Good morning all... I have a 2008 Ranger Sport 4x4. I noticed yesterday that when I stepped on the brake pedal it felt like nothing was there until I step a little harder then it was like full brake application. The truck only has 63000 on it. Then every once in awhile it would be normal ie very light brake application and slows like it should. Then back to same issue... Any thoughts about this??
The system is just hydraulics so if it's taking extra foot pressure to engage the brake pads you've got something hanging up somewhere. A stuck caliper piston is a good possibility and if the truck pulls to one side when braking that's usually a dead giveaway. If the steering is not pulling it could be something further upstream like the master cylinder hanging up or fluid gummed up in the line. Has the fluid ever been changed? Hope you get it solved.
if there was leakage the fluid level would change in the master cylinder. It is still same level. some days it works perfectly fine. Then at times it isn't
I have nothing specific to add, but your description sounds like a master cylinder problem. If it was a wheel cylinder problem it would either brake very unevenly or lock up one wheel, not affect the whole system behavior. Maybe your flushing of the brake fluid knocked loose a corrosion particle? Did you flush enough to get the old fluid out of the ABS unit?
