06 ford ranger, 2wd 9 inch brakes. I purchased all new shoes, drums,wheels cylinders, springs etc. I purchased the truck and realized the back brakes weren't working properly. So I bought everything new and replaced it. I still have the same issues as before. I bleed the rear brakes, cylinders. I have my son putting a lot of pressure on the brake pedal and I can still spin the rear wheels pretty easily. I have adjusted the shoes out enough where there is a slight rub when the wheel spins. The ebrake is about 1/3 from the floor and that docent hold the truck on my not so steep driveway. I'm lost. I have zero Leaks. bleed each cylinder till the air was removed. the brake pedal itself is firm like it should be, not spongy. No leakes near the master cylinder. could it be the portioning valve? anyone else have any similar issues? My 16 year old son is driving this and I wanna get it fixed asap.

 

Thats a good question. P valve. Curious what Don will come up with

 

You adjust the rear brakes by holding out the Parking brake release handle and pumping the Parking brake pedal until its not going down lower any more, you can not over adjust them
Also every time you back up and use the regular brake to stop it will adjust the rear shoes
Just FYI
Same on all vehicles, foot brake or hand brake

Remove the cap on the master
Do NOT touch brake pedal in the cab
Open a rear bleeder screw, right side first
Should have a slow steady stream of brake fluid, with no air bubbles, close bleeder
Do left side now

This is called gravity bleeding, brake fluid runs "downhill" from Master to slaves or calipers
There are no valves to block the flow, its a straight shot from master to slave/caliper

If there is no flow from BOTH rear slaves then there IS a blockage in the one brake line to the rear, could be in the line itself or in the 4 wheel ABS unit in the engine bay, if you just have Rear Wheel ABS then that unit is in the frame rail under the front of the cab, many just by-pass this unit

 

thanks for the reply. I actually did the gravity bleed method after i installed the new wheel cylinders. Then after that I bleed them both one at a time using my kid. I prob did it at least 25 times per side to make sure I had no air bubbles plus I wanted to flush out the old nasty fluid. I will try it again and I will also try the ebrake method. It hasent moved and he’s been driving it for a week.
