I know there is talk about the procedure of bleeding the brakes onthe Q, dont think i heard a definite answer as how to do it, or maybe i mis-understood!I have done brakes a 100 times never had this complication.S0 can you not just pump pedal and bleed air/etc. out of bleeder valve on calipers? thats what im trying now, my pedal is going all trhe way to the floor after pumping and adding fluid 2 or 3 times? whats the clicking noise heard in shifter area each time i press pedal? does key need to be on? thanks for any help.

Brakes haven't really changed much in 20-30 years other than ABS.

The best machine we ever bought was a BG brake vacuum unit uses shop air to suck out old while automatically refilling master cylinder.............connect to bleed screw let it chug chug for a few minutes then close the valve. Then move to another bleed valve...rear to front finally the abs pump valves................done in 15 minutes requiring no one pushing on pedal.................doubles - triples productivity.

Plus no mess as all used fluid is stored in a 10 gallon tank and a new liter is poured into system for each exchange and gratuated marks tell you when to move to the next valve.

Here's a used one for $750 but you'll have to do 100 per year to get a fast payback: We broke even in the first 6 weeks considering our labor rate!http://denver.craigslist.org/pts/594350777.html

IIRC, the sequence for bleeding Q brakes is RL ("R" = Rear "L" = Left), RR, FR, FL.

For the acronymically challenged, that's Rear Left (Rear Driver's Side), Rear Right (Rear Passenger's Side), Front Right (Front Passenger's Side), and finally Front Left (Front Driver's Side).

I wonder if you could use it to replace your transmission fluid?

Also what does a brake flush do? Brakes Plus usually talks me into getting them!
