brake flush
I there a good how-to on flushing the brakes? I need to do this soon. I just had the pads replaced but the brakes are still spongy and requite lots of pedal travel before they begin to stop the car
TIA

Were the brakes like that before the pad change?
If not, take it back to the mechanic to have them inspect the work. There might be an installation issue. What pads did they install? (brand/model) For a regular pad change, they don't need to open the bleeder valves, so there shouldn't be any more air in the system after they changed the pads. There's nothing wrong with bleeding the brakes, however I'm not certain it will address your issue.

try bleeding brakes
get someone to pump the brakes for you while you open and close the bleeder valve.
make sure your brake fluid resovior is full before you do this.
have someone pump the brake pedal 3 times and on the third pump hold the pedal down
as they are holding the pedal down, open the bleeder valve (you might wnat to get a short hose so that brake fluid doesnt fly everywhere) and let fluid rush out and collect in a small water bottle. then close the valve off. When you open the valve, the brake pedal should lose pressure and go straight to the ground. repeat this process until the fluid that is coming out of the bleeder valve looks like new and not brown and old

Re: try bleeding brakes
Where is the bleeder valve? What kind of brake fluid should I buy and do I simply put that into the reservoir to top it off after bleeding the old fluid off?

Just be careful. My old brake fluid reservoir was quite worn and the pressure bleeder caused it to crack. This is a pretty common thing for Audi/Volkswagen. Look for cracking near the windshield side of the reservoir. A new one just snaps into place, but it will cost you about $50.
