Resolved Brake Bleeding process...

[AWD Lox]

Today after work I am going to change my blown out two front calipers. Do I need to bleed all four of them when I am done? Also what is the proper technique if I need to bleed all four? Do the back right then back left then front right and front left first, ie starting the farthest away? Thanks guys..

Yes all 4.
The process is...
Right Rear
Left Rear
Right Front
Left Front

Start furthest from Master Cyl and work closer. And have PLENTY of brake fluid. Like 3 32 Oz bottles.

Sounds good. I appreciate the response..my dad and I had just never done a car with 4 wheel discs before..I wonder if I will be able to get to the bleeders on the back without pulling the wheels..that would be nice...

Be careful when you are removing your rear bleeder valves. If your car is from a snow state and hasn't had a bleed job done recently, that valve can rust into the caliper. I ended up breaking the tip of mine off trying to do that and I had to drill it out and get a new one.

The best way to do it is with a hand held vacuum pump. Crack open the bleeder screw and put the pump on it and just go to town, no need to bleed in order. The only thing you need to watch for is keepin the master full of fluid or else you have to start over.

Not correct.
Bleeding in sequence ensures that you REMOVE ALL the old fluid. And have -0- air bubbles. He is replacing 2 calipers, he is going to get air into the system weither or not he means to.

so do not post crap like that.

Pay special attention to the rear bleeds if you are from a state that uses salt on the roads mine were so far gone when we cracked them that I ended up having to buy calipers for the rear of my car. We could not extract them any way at all.

As for bleeding if you do a seach for brake bleeding and search the user name "oldman" he has an excellent procedure for the dsm.
