Brake failure my pedal is on the floor brakes not stopping the truck?

Good afternoon,

If the fluid is good and you have no pedal, most likely the master cylinder has failed.

If you open a bleeder, does fluid come out with the pedal depressed?

I'm not able to do that. I'm not trusting Brake Masters answer because I can't afford to replace entire or rebuilt ABS as msgr is suggesting. Or he said bring title to him so he can dispose of truck.

Thank you for quick reply. I'm doing some research. He says brake fluid is contaminated but the test he showed me, anyone could do as a ruse.

Sounds like he wants the truck.

I would replace the master cylinder and bleed the lines of all air.

Is the gasket under the master cylinder swelled up?

A bit.

Good chance there is a petroleum product in the fluid. It has failed the seals in the master and possibly the calipers and the wheel cylinders.

Thanks Roy! I went to a reliable salvage guy yesterday and he has several ABS for $100.00 vs $450.00 for rebuilt acquired by brake masters. He also has a good mechanic.
Thank you so much for your continued assistance and 'reassurance'. Have a blessed day!

You are welcome.

Always glad to help.
