Brake Reline
« on: November 10, 2013, 07:02:06 AM »
Does anyone know of where I can get my brake shoes relined? It is for the English hub for a 1938.

Check with a decent brake shop . They should be able to get the job done .

Or , I think Wayne sells linings .

Are they the same size as the later Simplex brakes?  If you look in the "wheels & tires" section, in the thread titled "Brakes", I've got some step by step photos of re-lining brake shoes.  Wayne sell new linings, but I dont know if they fit the early models too.

Post some pictures!  These early bikes are very rare and we would like to see what the early brake looks like.

Those parts are well rusted . You might consider dropping them into a vat of Oxalic acid .

Here's an excerpt from my build thread :

Quote from: pd
I rec'd my order of wood bleach ( Oxalic Acid ) and thought it best to test it before I subjected my fuel tank for rust removal .

I mixed a rather mild solution for the test . Here are some before and after pics :

Before :



After :



The parts looked almost this good after just a couple of hours bath , but I left them in over night to see if the deep reaches would be 'taken care of ' . The pulley was totally rusted .

I pulled the parts and rinsed them in a bath of hot water , then let them dry . The Oxalic acid seems to eat rust and leave a protective coating . I wiped some of that coating off the rear brake plate . Also note that the acid does not effect painted parts ( a big plus ) .

This was an experiment for me . My Simplex had a bit of rust forming in the gas tank . Not too bad considering the bike is 55 years old . I'd read that different acids worked for removing rust .

I used muriatic acid to clean my XT350 tank with decent results . That tank did flash rust and I retreated it and then neutralized the acid ASAP . It still formed a small amount of flash rust . I'm running it with an in line paper fuel filter and haven't had any problems .

The Simplex tank is a bit more rare and harder to find . I was reluctant to use muriatic acid in it for those reasons . Through research , I read about oxalic acid , sold as wood bleach . Oxalic acid is a lot safer to work with , but still requires due caution ( READ THE LABEL ) . It's not nearly as toxic as muriatic acid . It does NOT harm painted surfaces . It just eats rust and leaves a protective coating on the steel after being thoroughly rinsed with water .

I used a diluted mixture from what is suggested , which is 12 ounces to 1 gallon of water . I used 12 ounces to 2 gallons of water . Being as the solution was weaker , I left the mixture in the tank twice as long and the results are shown below .

This is what I used :



Here's the rusted tank :



And, here's the tank after being filled with oxalic acid for a couple of days :



This stuff really does work great . I'll use it from now on when treating rust .

Is this something I would pick up at Home Depot? As rusted as the parts are they still turn free!

Wood Bleach ( Oxalic Acid ) ?

Yes , any decent hardware or home improvement store should carry it , or at least be able to get it for you . It's also available on Ebay :

Hard to see from the photo, but your existing lining may still be serviceable.  If you do replace them, be mindfull that they probably contain asbestos.

Thank You! I'm going to pull them apart and clean them up. To see what I have to work with.
