Excellent video on brake repacking

It works well but i always clean out the old grease first

I know you do! Like me, you are a fussy guy, that goes the distance to do things right. :)

By saying, old grease, that may not have been removed properly, I'm taking about the 98% of people doing these simple tasks. That tool will force out contaminates they left behind.

Dang Old Biscuit, that thing is affordable. Just ordered one on amazon.

I have had the similar unit for around 35 years. It works well but i always clean out the old grease first

With a tolerance of .015" on the brake drum runout, I don't want the self adjusting brakes. If you are lucky and get good drums, they may work, if you are not so lucky and the drums are near maximum tolerance, they will never adjust properly.

The only time I ever use the grease fitting is during the spindle cleaning. That grease passage will collect dirt and solvent during the cleaning process and needs to be flushed.

Wearing only one glove.... what's the point! LOL


I've never seen those brake show gauges. With his brakes being "self adjusting", that tool wasn't necessary. When I installed self adjusting brakes on my cargo trailer last year, I used the adjuster wheel to dial them in a little bit then left the self adjusting function to do its job to get all 4 brakes set appropriately.

I use a much larger piece of cardboard to contain my mess and keep it off the concrete driveway I do these projects on.

A better video on bearing repacking.

I agree, he put way too much grease on the spindle, and the seal will push it off in that area.

I think he was trying to demonstrate how to turn the wheel, when using the grease gun on the EZ lube. However, after doing a proper hand greasing, there is no need to add more through the zerk. You should be good for several years, before any further greasing, if no brake symptoms occur, requiring hub removal.

The only issue I have he put way more grease on the spindle than needed and in particular the seal surface on the spindle. With the amount he used there will be grease pushed into the brake shoe area as the seal goes over the spindle and seal area. This grease will then fall into the brake area and contaminate the brake shoes.

A very light film of grease is all that is needed and a very light grease or oil on the seal surface. I have always used a very light film of motor oil on my grease seal both the seal area and the outer rim so the seal will not gall when pressing into the hub.

That was really bad i would advise anyone skeptical about mechanical stuff and greasing bearings to find a different video.

I thought his small cardboard box scheme was lame...

In the SE garages mainly occur in these new mini-mansion subdivisions. Most folks living out on acreage don't have one tho some have a pole barn. And pole barns often have dirt floors.
