    Default 2000 Silverado 2500HD 4x4 6.0L - Brake issues

    Hey All, Im a Newbe, so forgive me if I started this in the wrong place. I am having issues with my Brakes. I had a full peddle one day on the way home from work and the peddle went to the floor and then came back when I tried again. Then the other day they went to the floor almost and only the front brakes are now working. I have a lift, so I checked under the truck and found no leaks, the reseivor is full! The pump for the booster is full. My first through was the booster, so does anyone now of a test to insure I am going in the right direction? Thanks for your help!

    Sadly brakes aren't my thing, but I wanted to take a moment to welcome you to GMTC ... from Roxboro, NC!

    Maybe @Pikey can give you some advice?

    Welcome to GMTC! I have a few questions to ask about your brake issue. Is the master cylinder full of fluid? Open it and take a look inside, is it full all the way across? I ask this because the inside of the reservoir is divided into 2 sections. Now look where the master cylinder mounts to the brake booster, do you see any fluid there (at the mounting point)? Does your truck have a hydrobooster or a vacuum booster? Are there power steering lines running to the booster or does it look like a pancake style air compressor?

    Thanks for your reply, I have a full reservoir, I haven't checked the mounting point for leaks, but I will do so, and I have a hydrobooster and the reservoir for the hydrobooster pump is full too. I feel the Master cyclinder is the problem at this point. I have order a new one, I will let you know if this has resolved my problem. Thanks again for your reply.
