Hello
I am in the process of replacing rear axle shaft and went ahead and replaced drum shoe pads and 1 new brake cylinder on driver side rear
Brakes bleed fine
But when i went to hold the pedal down while car was jacked up the niether of the rear brakes expanded at all or hold the wheel, Is there something im missing?
Are the rear brakes not always active??
It has ABS on only the front rotors i beleve, didnt see anything on back

Rangers have Rear ABS(RABS) or 4 wheel ABS(4WABS)

Yes, the ABS module can restrict flow to rear wheels if it gets clogged up, but probably would not have bled correctly if so

Pickup trucks use 70/30 proportioning for braking
70% goes to front brakes 30% to rear brakes
Cars and SUVs use 60/40, just FYI

When you press on the brake pedal the rear wheels should stop spinning, if the rear shoes have been adjusted correctly
There is a "star wheel" adjuster on each rear brake that will move the shoes closer to the drum each time you back up and stop using the brake pedal
Or each time you press down on the Parking brake pedal
It can not be over adjusted it won't move any more once shoes are in correct place for their thickness
There is a left and right "star" so they need to go back on correct side

Thanks for info, I bleed the brakes more and they've started to move, the passenger side brake only moves the forward shoe and not the rear, must need a new cylinder also

Also after replacing the rear cylinders I will bleed the back drum brakes again, is it necessary to bleed the front brakes aswell?
