Default Gravity Bleeding- Rear Only?

All,

I need to change my rear calipers & pads on my 78. Can I simply gravity bleed the rear brakes only without screwing the fronts up?

Also, its my understanding that to gravity bleed you simply mount the calipers & pads, open the bleed screws, remove the master cylinder cover and let nature take its course (while making sure the master cylinder does not go dry). Is it that simple?

Thank you,
Dan

Yes, you can just bleed the rears - it is separate from the front. That's pretty much how gravity bleeding goes. Only do each of the bleeder screws individually.

But gravity bleeding the rear calipers takes some time

Good question as I hate bleeding brakes... I have noticed that my calipers which are Delco reman's have a bleeder on the inboard and outboard side of the caliper... does that mean both have to be bled out or just the outter, which would be furthest from the master cylinder?

Both halves of the rear calipers have to be bled. Bleed the inner half first, then the outer.

Yes; gravity bleed. Resist the urge to depress the brake pedal until you have plenty of fluid at both of the rear calipers.

It's always been my understanding...to bleed farthest from the master (outer) to closer (inner). Must work both ways as I get the hardest peddle ever, and I'm using Dot 5 Muddy

This is just one of many endless debates, I like to bleed closest to the M/C first inner than outer, which for me is LR that RR. Than LF than RF. PG.

After replacing my Rear Calipers and Master Cylinder, it was helpful using a rubber mallet to tap on the calipers to remove trapped air. But we did use a power motive bleeder unit.

Service manual says:

LR, RR, RF, LF
On the rears, inner halves are bled first.

service manuals contradict issues from time to time, evidentally both methods work as many do it your way, however i have always done the opposite....rr..lr..rf..lf....longest line first.....
