Guys I'm about to go change my rear left caliper. Will I have to bleed all four sides when I'm done or can i just bleed that side only?
Thanks,
Nick

You don't have to bleed all 4 but I would recommend it. Always good to know you have clean fluid in the system.

Yeah its alot better off if you bleed all four just to make sure. And even if all the air is out at least you will have new fluid all the way around.

Thanks guys I'll bleed them all today.

Start with the corner furthest from the master cylinder,working your way towards it.

Get some rust penetrant on those bleeders and use a line wrench if possible. They can be a mother.

thanks everybody, the brakes are real nice and firm now, and no more frozen calipers :D

That's actually incorrect for our cars. You should bleed RR, LF, LR, RF (in an X). The brakes are connected by the diagonal and the best bleed is done such.

If your brakes are firm by doing it farthest to closest, don't redo it... but if they are a bit mushy, that's the first thing I'd try.

Depends on what year car you have.
IIRC, the B13 order is different than the B14 order.

Sorry for the confusion, the original poster has a B13 and so do I. I don't remember what the bleeding order for a B14 is.

I did it the same way maxQ mentioned (RR, LF, LR, RF ) and everything is all good.

If you are planning on replacing the pad and/or rotor while you're doing the caliper, you should go ahead and do the other side as well. Better safe than sorry IMO.

Meanwhile, If you are going to change your fluid, go with Ate Super Blue brake fluid(DOT4). It has both higher wet & dry boiling points as well as a lower(better) moisture absorption rate than fluids like Motul RBF600. Furthermore, since the fluid is blue, it is easy to tell when the fluid has been changed. As you are bleeding your brakes the the fluid color will change to blue. Should you change it again at a later date, use the Ate Type200...same fluid, different color(yellow).
