It's a 2008 vw beetle and I would like to get some feedback on this. As I was driving I had to stop very fast as I did that I herd a pop then the brake pedal went to the floor but after pumping the brakes the petal was very hard, and make a loud hissing sound when I hit the brakes. The car doesn't stop very well. I have checked the brake booster vacuum line for cracks, Nome that I could see, but I was not able to get it all the way off the car. I can get the check valve side out but not where it hooks the the vacuum pump. Any help would be much appreciated.



F.y.I . I'm new to the forms

I would check the brake booster hose, vacuum pump or the brake booster itself for failure. It has been said; that there is a vacuum pump, that supplies vacuum to the brake booster. This pump is failure prone and expensive to replace (failure is usually indicated by leaking oil); if the pump fails, you might consider this delete kit from USP Motorsports. It eliminates the need for the pump and you get vacuum; direct from the motor itself. You might contact the vendor; to confirm, that it works with the New Beetle.

Brake booster hose: this is a aftermarket hose; which is cheaper or you could call your local vw dealer, see how much one is from them. Note: use your VIN# to get the correct parts.

Well, make sure to diagnose the problem; it may just be a vacuum hose or the vacuum pump, may have failed. Again, I would contact USP Motorsports and confirm their kit, works on the New Beetle.
