Brake Help

Need advice on the status of the brakes on my 2013. They start off working fine but after driving it several miles the brakes seem to be very ineffective. The pedal will depress to the floor and will need to pump the brakes to get any stopping power. Fluid level is fine the truck has 80K on it and spends a lot of the time in the garage(gas mileage). Do you think it's time for a brake job with its mileage or what?

 

Master cylinder

 

The possibilities for this happening, ordered most likely to least likely:
1. Master cylinder: Failed internal seals will allow the pressure to bleed off but since they leak internally you won't see any fluid loss.
2. A bulging brake line: If you step on the pedal and one of the soft lines expands, you'll have to keep pumping to overcome that.
3. ABS issue: it's not all that likely, but sometimes failed ABS components can cause an issue like this, but usually it's to a very limited degree.

Bad pads, worn rotors, seized calipers, etc. won't cause this problem.

 

The soft rubber hose brake lines.........replace all 6 hoses with Stainless Steel hoses and you will be amazed how high and solid your brake pedal will be. About a $125 repair if you do it your self........if not figure another $100 for labor.

 

Wow, great help and will keep everything posted as to the fix. Thanks so much!
