Little Help?

chevygrrrl · September 21, 2009

Hey there I am new to this forum.....Just a quick question. I have a year 2000 2500 GMC Sierra and there is no pressure behind the brakes when i push on the pedal, it goes completely to the floor. I thought this may have been caused by an air bubble but when i am driving the front driver side tire is making a slight noise, it almost sounds like a rock is stuck in the tire. However this is not the case. My front tires are also slightly angled inward towards the cab......Does anyone know what these problems could be? Thank you for your help

My guess is you have a broken line somewhere. Lines will eventially rot out if they are not protected annually or are not SS and will start to leak, causing a leak and your pedal doing what it is doing currently. That rock in the wheel noise could be that your pads are worn down and the rivots are going into the rotors. Not sure about the inward wheels, my guess would be out of alignment, loose bolts?

I wouldn't drive the truck like that, bring it down to a local repair shop and have it looked over.

Do you have a trusted mechanic at your disposal? Alot of times, you can face a huge bill for brake repair and taken advantage of if you do not know the shop and mechanics well. Just remember, when a brake pedal starts to sink down and feel soft/no pressure, it is time to stop driving the vehicle and get it into a shop asap. If you are gonna drive the truck to the shop that way, make sure you allow yourself plenty of extra time for stopping, and if you can avoid high traffic roads, take back roads or keep a great distance away from vehicle ahead of you. I had a freak accident earlier this year, where a RR Tie I was driving over popped up and damaged a small portion of my brake line when the tie was forced up in a verticle position and the force of the truck backing up caused it to make a loud thumping noise. Anyway, later that day my pedal went soft of me while driving out to a resturant and having to make a hard brake for a deer. I faced some challenges getting back home and driving to the repair shop the next day with steep hills because i live in an elevated area.

Could also be the master cyl going out

... don't drive it very fast or very far....!!!! you definitely need critical attention to your brakes... it is a scary situation when you push your brake pedal down and it goes all the way to the floor......

... if you can limp it safely to a mechanic shop do so, or else get it towed....

.. brake problems are relatively simple to diagnose and repair... (basically you have a leak in the brake lines, or wheel cylinders or master cylinder).... not necessarily cheap, but the problems are usually obvious to a trained/experienced mechanic....
