Bleeding brakes

A search gives me differing answers.

I have always been taught by the older guys that the proper bleeding sequence is to bleed brakes right rear, left rear, right front and left front.

With new cars, does this matter anymore?
 
It won't matter at all if you are just bleeding the brakes. If you are replacing the brake fluid then those instructions are in order of farthest from the master cylinder. However nearly all 'newer' cars have ABS. Nearly all ABS systems are closer to the front of the car so those instructions are still true. The best answer is whatever your factory service manual states, so check up on the online forums for your particular car.

In the real-world though, regardless of all what I stated above it doesn't matter. I still bleed in the order you mentioned except this past weekend where I got interrupted, got lazy and did it passenger rear, pass front, driver rear, driver front. I still sleep well at night.

Bleed the diagonal components. Right rear-Left front, Left rear-Right front. You are actually dealing with two separate systems. How long have we had that? About 30 years?
 
The first 2 posts are different answers!

Right rear and left front then left rear and right front is a new one to me.

What systems are truly diagonal? Chrysler did that in the 1960s when there were drums on all corners, but disc/drum and even disc/disc need radically different pressures front and rear. (They also want to engineer in understeer, guaranteeing the front skids first.)

+1. This is what I thought was the correct order.
 
Like eljefino said, there aren't any diagonal systems on modern cars. If you look at a lot of non-ABS vehicles, you will find one line to the back with a tee on the back axle to the two wheels.

Agree.

My cars didn't specify the order, but I almost always do the rears first then the fronts.

Most newer vehicles have 4-channel ABS and the order is irrelevant.

Every vehicle on the road has a diagonal or split braking system. That's why there are two lines coming out of the master cylinder. The DOT requires split breaking systems and has done so for about three decades.
