HI, I dont think it matters where you start as you dont run out of fluid in the master cylinder, if air keeps coming out keep bleeding that nipple. The longest brake line will probably take more bleeds. I usually losen the nipple then slightly nip it up then fit a ring spanner then the clear tube over the nipple & it feeds into a jar. The clear tubing is easier to see the bubbles & the jar is to catch & see how dirty it is, if dirty keep going to its clean in the tube.(dont use dirty fluid) The brake pumper should pump up the pedal a number of times then hold it down while you undo the nipple they should feel the pedal go down. They should say yep & you tighten up the nipple, they should feel the pedal becoming firmer each time air is released. Look out for signs of fluid leaks around the base of master cylinder, wheel cylinders & caliper rubbers. Also some pipes go into a block junction which has a switch with a wire coming off it, loosen switch & give a tap to reset switch. This should turn brake warning light of at the dash. Good luck GARYB in Oz!!!

First off, be sure your master cylinder is full of brake fluid. Now, starting at the driver wheel, behind or on top the caliper is a bleeder screw. Loosen this screw. The brake fluid may start running out on its own(gravity bleeding)if not then you will need someone to pump the brakes. Using a second person, close the bleeder screw and have them pump the brakes then hold the pedal down. While they have the pedal down, open the bleeder screw and then close it after brake fluid stops coming out. Repeat pumping and holding the brake pedal down then open the bleeder screw until you do not see any air bubbles coming out, should only take 2 or 3 times per wheel. Do the same for the rest of the wheels, starting at the drivers wheel then the passenger front wheel, then the driver rear wheel and ending up on the passenger rear wheel. Make sure your master cylinder does not run out of brake fluid or you will have to start over.

this information is incorrect. when bleeding you should start at the rear driver side wheel, rear passenger, then passenger and finally driver wheel.
