Doing the Brakes

[Mil-Spec]

It way past time to do the brakes on my 1979 K20 Suburban (My first 4x4). It has a dana 60 front axle with Warn Locks. Can anyone walk me through the procedure of pulling off the discs and the calipers? The discs are being replaced. Any other advice?

Thanks

There is a bolt on the caliper bracket that holds down a shim, take it out and tap the shim out the front of the caliper. this will free the caliper up so that it can be lifted out from the bracket.

In order to replase the (Disc) rotor you have to remove the lockout, on a Warns allen head screws are used to hold the cap in place. After you remove the cap there is a retainer ring around the outside of the hub, this needs removed also. If the lockout was installed properly then there should be a snap-ring holdin the lockout to the axle shaft, remove it. Screw one or two of the allen bolts back in and wiggle the lockout around while pulling it should pop out, now remove the spring if there is one.

Now the spindle nuts need removed, this requires a special socket with 6 prongs on it and can be picked up at any auto store. Remove the first nut followed by a washer with holes in it then the second nut, make sure you remember what way they came out there is a nub on the nut that fits inside the holes on the washer. With both nuts removed the hub can now be removed, this is a good time to check your bearings and races and replace if needed. Now that the hub is on the ground yuo have to beat the studs out. Use a hammer and punch or a lead hammer, if neither are avalible screw the lugnut back on a couple of threads and beat on it. Once the studs are out the (Disc) rotor will be free or the hub. Flip the hub over put the new rotor on and beat the studs back in.

Do Everything in reverse and repeat for the other side.
Have fun!

Thanks GL!!

That's a big help. I replaced the caliper as it was corroded solid . Really jacked up my 9" clamp trying to compress it, before I decide to stop and just replace it and bleed the system. Decided to save the rotor swap for next weekend. The PO replaced the caliper, pads and rotor on the driver's side but not the passenger. It not right, but I don't blame him. So now I'm able to run around town, til the week end. Feels great.

Not a problem, that's what we are here for.

a dana 60? I assume that it wasn't stock?

I'm new to 4x4s so perhaps I'm mistaken. Here's some pics you tell me.





Thanks

that's a corporate 10-bolt... found on 1/2 ton and 3/4 ton trucks from about 79ish to 87

If your calipers are leaking or frozen it's cheaper to just buy a new set... they don't cost very much

Thanks for the correction.

As for the calipers they have now both been replaced with re-manufactured units. The passenger side rotor still needs replaced as its extremely under spec. So I'm looking forward to getting into that here soon.

plan on repacking the bearings too then. Do you have a spindle nut socket? They sell them pretty cheap...
