Brake Pedal goes to the Floor
Hi,

After 2 week ends of wheeling. Mudding, water crossing.
My brake seems to loose it's performance.

The ABS lights come when I wash the car and goes off after some 2 or 3 starts.
I need to hit the pedal almost to the floor to brake it.

I planned to bring her to the my Denso dealer and get the brake systems flush, and replace with a new fluid and check all the systems including ABS.

What cam be the main problem? Master cylinder?
The brake works fine before the off-road trip

Thank you

my guess is a brake line is stretching ALLOT, maybe it got caught on something while off road.... either water water / air / stretched line (s) are the most likely causes here, needs to be taken care of before driving on the streets obviously, good luck! please report back what you find

Also check your brake master cylinder. Often times when the pedal goes to the floor, you either have air in the line or the master cylinder is bad. You can also check to see if there are any codes that you can pull. Even though you do not have a Check Engine Light, you may still have codes that could tell you where the issue lies.

And like the previous post talks about, take a look underneath and check your lines. its possible you punctured/tore a line as well. And I would strongly suggest to keep it off the road.
