about to bleed brakes !!!
 

Just did a major brake service on my A6. Rebuild front 2 calipers, replace all 4 rotors, all new pads, all new brake flex lines and new master cylinder.... all put back together and about to start bleeding.
Anything special I need to know about the Audi ? pretty funky looking little cap in the reservoir, looks like a buble trap of some kind.

Just wanted to make sure there wasnt an caveats I need to be aware of ..

All the best ..

BTW putting ATE gold in the car ..

Pressure bleeder is the best but it is expensive. I use mityvac. Some use good 'ol gravity method, but requires a lift.

I was going to use the old .. "pump till your leg falls off your partner then get another one" method.. I m not even sure grivity method would work .. and it would take for ever..

I was going to work from the fartheest wheel from the cylinder .... the usual stuff, I abve never done a mster cylinder before though .. I hope I have enough fluid.

$30 vacuum pump can save someone a leg and keep the friend a friend too. :)

I've done the gravity method, works fine.

i asked my buddy and he said he would rather have 30.00 in beer .. damn Canadians .. but i think your right a pressure bleeder may be the way to go given i have 5 cars and replace fluid every 2 years.

J.H.
how long did the fluid take to come through ? did you just pour it in and open up all 4 bleeders till it came out ?

I also strongly recommend pressure bleeding. Motive Products makes a very good one for about $60, it will last a shade tree guy a lifetime of bleedings. This process forces the fluid through the system in the normal way and it is good for the ABS valves and works much better for me than vacuum. All you have to do is fill the bleeder, connect it to the master cylinder cap, pump up the bleeder to 15 psi and go around opening the valves one at a time, order doesn't matter. Keep the pressure up with a few pumpings during the job. When done, tilt the bleeder away from the pickup tube and bleed until the supply line is empty and disconnect it.

Sounds reasonable .. I didn't understand your last line as I have not seen one .. so what's the deal with the little yellow twist off cap beside the main fill opening on the reservoir. ? does that stay on and sealed during bleeding?

The bleeder is like a pump up lawn sprayer, it has a pickup tube inside that goes to the bottom of the container. To clear the bleeder line so that you don't make a mess when you disconnect from the master cylinder, you need to keep bleeding with the pickup not in the fluid so the supply line clears itself, it's clear tubing so you can see what's happening. As far as the little yellow plug, I assume its for a factory attachment of some kind for pressure bleeding but not sure, someone probably knows, I'm new here.

cool ...lost the big ass 7" bolt that holds my master cylider on so everythiong is on hold for a while .. how i lose a 7" bolt i have NOOO idea..
