Got to do a brake job on C60S
 

Hi Guys

Have to do a brake job on my 1942 Pat 13 C60S before the spring driving season. The master cylinder has just started leaking which means it is time to replace the piston cups. Should be straight forward while I have the drums off will be checking the brake linings to see if after 73 years it is time to reline the shoes.

So before I start does have anybody have any questions or need detail photos of any particular parts?

Cheers Phil

Good preventive maintenance.....
 

Always better before the bump than after.

Hi Phil

You carry a lot of weight on that rig ...... good point to do a major overhaul of the anchor.

Some details of the inside of the brake / backing wheel.... looking for wear patterns....... some one was looking at my tools on the rack in the barn and said...pointing to the brake spring pliers..... have one of those....not sure how to use them!!!!

Are you relining....... or degreasing your linings if still good..... how good is good after 70 years. The relining shop here in Ottawa, when I told them what I was restoring.... strongly recommended installing rivets at the leading and trailing edge of the bonded new linings....... in case they let go due to limited usage..... apparently the bonding can break loose after years of storage.

How do you flush the lines ....... do you use the expensive spary cans from Eastwood or have a trick of your own.

Will you consider going with Synthetic fluid in a major rebuild???

Besides a visual inspection of the steel/rubber brakelines.... how can you test them.

Will you be washing and repacking the wheel bearings???

Do you repaint your drums...... will they get turned down and the new lining arced.

That project should keep you greasy and busy for a few days.

Just be careful with the heavy 20" wheels.....don't pop something.

Here is a picture of the brakes on a C15a.......
 

Some years ago I took apart a rolling chassis of an ex water truck.

Apparently the brakes were not functioning very good.

Can you find what is wrong with this picture....?

Cheers

Wonder how long it took for that bolt to get caught up there? Looks like it's done the rounds a few times before lodging. I've seen those wheel cylinder shields smashed up before.

On the M35Cdn (MLVW) the shields would often be lifted up to be able to pull back the rubber and check for how much leakage was occurring. The shields would be bent back down, but of course they would never go back to the original position. They would then get rubbed by the drum, and occasionally could separate. An instruction came out a decade or so ago to simply remove them. Not having them did not seem to make a difference.
