My truck brakes work great after driving for awhile but if it sits over night the next day my brakes suck the first few times being used. Anyone know whats going on? I have a 1990 4cyl auto trans 4x4 with working a/c, no lift and only running 235/75-15 at's

Check all the vacuum lines to the booster.

Sounds like a leak in the brake booster system. http://personal.utulsa.edu/~nathan-b.../2troubles.pdf

Just what do you mean by "My Brakes Suck"??

pedal goes almost to the floor??

Losing any brake fluid?

The pedal is very hard to push??

one or more brakes grab till the gear oil or grease is burnt off??

All lead to quite different issues.

I have never lost any fluid. All brakes are grabbing. Very easy to press but feels like no pressure the first 3 or 4 times pressing the pedal. Brakes squeak the first 3 or 4 times but after that they work great. I could drive it all day and there great after that.
