Need to bleed my brakes after replacing master cylinder on '87 240 dl wagon. Questions is...on the front there are 3 bleed screws. Do you bleed all 3 at the same time or one at a time? If one at a time is there a certain rotation to do it? Also if someone can tell me the roation for bleeding either way.

With 195k miles is it a good idea to replace calipars as well?

Thank you so much.

Since you replaced the master cylinder you should bleed the entire system. According to Haynes (74-99 240's) the sequence is:
1.) Left rear wheel; 2.)Left front wheel, upper; 3.) Right front wheel, upper; 4.) Right rear wheel; 5.) Right front wheel, outer; 6.) Right front wheel, lower inner; 7.) Left front wheel, outer; 8.) left front wheel, lower inner.

Have fun......hope you have an assistant .

After thought: you do know to use a see through plastic hose connected to the bleed nipple and the other end in a jar with some fluid in it ... so as not to get air in the lines ??

The way I do it, and it has always worked, is to attach plastic see-through hose to all of the bleeder nipples on the caliper and run them into a large jar that is half filled with brake fluid. Open all of the bleeders on that caliper and have someone pump the brake pedal slow but steady until no air bubbles can be seen. Be sure to keep adding fluid to the resevoir so it does not go dry. after all of the air is out, have the pumper hold the pedal down and then close all of the bleeders. Start at the caliper farthest from the master cylinder and work up to the closest to the master cylinder. Be sure to keep the plastic lines sumerged in the brake fluid so air will not re-enter the system.

This procedure is really quick and easy.
