squishy brake pedal
How does that song, Wolf Creek Pass, go? "Steppin' on the brakes was like steppin' on a plum!" Or something like that.
I started the truck today and the pedal went straight to the floor! They held and when I released the brake the truck rolled in reverse like it should. Afterwards the pedal was squishy, but not on the floor and still working. Any ideas??? '66 custom camper 350 engine power drum brakes Power assist steering auto tranny. |

Re: squishy brake pedal
^ As above...
If you don't see any fluid on the wheels or outside the master cylinder, suspect the internal piston seal of the master cylinder gone bad. The cup seal allows fluid past it and the brake feels mushy. Don't take any chances of complete failure and replace it. They're not expensive and fairly easy to replace. Just remember to follow bleeding directions of the master cylinder carefully and also bleed the brakes.

Re: squishy brake pedal
I should have added the reason for me stopping was "that old lady" that pulled out in front of me causing me to stand on the brakes hard ..that's what led to this...lucky for the wide slot in the road... that kept me from hitting her

Re: squishy brake pedal
Took me a while to get the lid off the MC. Yeah, no fluid. So I checked around all four wheels after filling it. Looks like the left rear might be weeping. She gave good pedal today and stopped on a dime with nine cents change! Will have to go around and work on all four cylinders. Might just replace all of them including the master, better safe than sorry. Thanks for the hints.
