Title: Removing excess powder coating from Brake Hub
Post by: McCabe-Thiele (Ted) on March 16, 2024, 03:47:36 PM
After doing a few household chores today I had half an hour to spare to look at building up the brake back plate with the brake shoes.
When I fitted the brake shoes there was no room for a washer between the shoes & the split pin - the original twin link item was missing so individual washers were used instead.

The powder coating appears to have raised the brake shoes both at the lever end and the pivot pins. As a result the brake shoes do not sit where they were before.

I do not have a Dremel tool so what is the easiest/best  way to remove the powder coating in the three affected areas. i.e. the brake shoe pins and the bottom lever actuator boss.

Is a Stanley knife blade likely to work (feels a tad dangerous) or do I use a small plastic cutting wheel in my electric drill?

Ted,

I would use an electric drill and a small grinding stone from my cheapo Lidl Powerfix milling/cutting/polishing tool set.

Same as this one currently offered on Fleabay:-

A Dremel type tool is probably something I should have bought over a thirty tears  ago when I was doing all my home DIY.

For how much I would use one today I can't justify the outlay - a recommended cheapo might be an option.

I think mine costs about £12 with assorted tools,

I use one of these. Did all my polishing and powder coating removal ( used a small grinding bit ). Hours and hours of fairly heavy duty use and I likes that it was 170w. Flexible extension is available and really useful.
Highly recommended.

My Von Haus tool arrived yesterday so I quickly made short work of removing the powder coating from the three affected areas.

On fitting the brake shoes again it was clear that there is still not enough room to fit even a thin washer between the split pin & brake shoes. I can only assume that the after market brake shoes do not allow for the fitting of a washer unless fitted a very thin washers with very very thin split pins.

As the rear brake worked previously I'm happy enough that the split pins will hold the brake shoes in place. On the plus side the new tool will come in handy for quite a few other jobs in the garage.

I found after market shoes are to wide at the pivot end,


I normally use a file to remove some alloy so the double washer and split pins fit,

Just care needed to get the shoes to fit square

Do you just file it from the top John or file a tad off either end?

Only the pivot hole,

I took 0.5mm from both sides of the shoes

Use mine all the time Ted eg wire brush for cleaning up threads. Flexible drive shaft makes it easy to access tight areas and do fine work. The metal cutting discs you can get are great for quick jobs and much has been written about the plastic  polishing wheels recommended initially by Ken. You won’t regret getting one.
