Rear brake bleeding struggles

[YakkoWarner]

You have a k20? 1974 would be a full float 14 bolt. 12/10 bolts came in half tons.

Inboard rotors/drums are not as convenient as if they were outboard, but not really a big deal overall.

Buy the correct socket for the axle/spindle nuts.

If drum needs to be removed to be changed or turned, it will require pounding all the lug studs out and reinstalling them (personally I’d replace them).

Technically, on a drum brake full floater, you don’t even have to take the wheel off to pull the hub/drum, if you were only needing to change a wheel cylinder and no work needed on drum itself. Pull axle shaft (make sure you have enough room to slide the shaft out), spindle nut(s) off and slide assembly off.

Not something most do on smaller trucks, but class 8 and medium duty’s that pretty normal to pull the hub, drum, wheels as an assembly.

Other than that they are not really any different than any other self adjusting drum brake setup.

Also, I’d replace the rubber soft lines, if they have not been replaced in your ownership or a known date of if/when they were replaced. One of those fairly cheap parts that get overlooked and can cause plenty of headaches.

Don't you have to remove something from inside the center section to enable the axle shaft to slide out???

All fluid for rear brakes comes down 1 line,through 1 hose to a tee which branches left and right if you have fluid to 1 rear the problem is after the tee at the rearend.So,the steel line,or the wheel cylinder.

Edit already covered. Should have read more posts

Yes it was covered but you made me think of another question. Where is this light? I didn't notice anything and it's possible the bulb may even be out but that would be really helpful to know.

No, not on a full floater. Remove the bolts on the axle flange, have a drain pan ready, slide axle out.

Semi floater C clip type axles yes, like 14b SF, 10,12 bolts, the cross pin must be removed from the carrier to push axle in to remove c clips to remove axles. But all of those are outboard rotors/drums so no need to pull the axle to pull a drum/rotor.

Semi float axles can also be non c clip type, like the Ford 9", Mopar 8.75, and some others.

14b SF axles, if you note on the end there is a groove for the C clip

I put up relevant info on post 18 after my edit. As for the light put on the emergency brake a light should come on in the dash,same light,same bulb.So that would be an easy first check.

If and when you go back together with the hub....DO NOT drag the seal over the threads on the housing........you will be taking it back apart to fix the differential oil leak that's ruining your new parts inside the drum!!!

New fear unlocked.
