drum brake question	Sign In

Hi,
I'm doing the rear brakes on a '95 tercel and when I pulled the drums off there was a lot of grease on the end of the axle as well as in the hub (where the inner wheel bearing is). I wiped a lot of it away and was wondering where to put new grease. Should I apply it to the axle or put it in the hub?
Thanks

The bearings themselves should be packed with grease internally with some extra inside the drum on the race before it is put back together. There should be nothing outside of the seal or anywhere near the brake or drum surface.

Hmmm - I thought by '95 greaseable bearing were done for hubs you can't mess with but no problem. The "inner/outer bearing" idea is still out there now mostly trailers. Was the norm for almost every non drive wheel for ages on top of ages.

You grease the bearings themselves each leaving just some in hub and on axle, install a new grease seal, set adjustment them with the nut*, install new cotter pin or however it's locked, put dust cap back on and not worry about it too much unless there's a problem. Grease should never be allowed on the brake.

Someone before you might have been a bit heavy with the grease which really shouldn't be a problem. Is there a problem? Why were you in there to begin with and you do need to for even inspecting brakes and some will suggest periodic re-greasing that type bearing concept and should for some depending on use, miles or time.

This is so primal it pre dates cars at all. Wooden wheels on the carts pulled by horses did this that way. Trouble now is everyone forgot and it requires setting them and knowing how or you will cause problems. Too tight they'll burn out and can spray grease around as that makes them too hot also. Too loose with free play the integrity is lost, brake may not behave properly depending on how far off it is.

There will be listed torque specs for how tight to set them with that nut and back off some % of a turn type thing. Why are you in there?
