Thanks for your input,

Here is a picture from the IHC parts catalogue. Look at 38,39 40 This is likely the way I would attach a spring. It worked for IHC for decades.

Thanks again for all of the great input.....took your suggestions on the brake rod, worked out great.( almost scary, not used to things working out the first try...). Master Power Brakes advised me that no return spring is needed as there is one built into the master cylinder, but, after assembling the whole thing the pedal does return although it doesn't have a lot of force. I think once again I will yield to Nikki's suggestion and also use the original return spring setup....
Also completed my mechanically actuated brake switch, which also worked out great....

Still on the list to do, brace the master cylinder mount that I made, finish the brake lines. The remote booster will be started once I get the front sheet metal back in place.

Everyone please stay safe,

Re: power assisted front disc brakes

This is what I used for a mechanical brake switch on my R120. It is from Ford and I got this from an F250. It mounts to the brake pedal where the push-rod attaches. It requires a little slack in the fit. When the pedal is depressed, the switch is forced against the push-rod.

original location causes axel interference.jpg
axle interference
I thought I would share a problem with the TSM Disc brake kit used on a '52 L110. Everything fits fine however the supplied stainless brake line rubs on the axel if installed as the caliper was designed. I intend to remove both calipers and grind a portion of the "wall" that was designed to hold the brakeline banjo in place so it can't move, so I can obtain a different angle for the supplied line so it will not rub.....I'm posting this before I grind to get input from the more experienced members.

THANKS

Re: power assisted front disc brakes

It looks to me like the line is too long. You have it at full turn, or near it, and it must be at almost full drop, as the shock is pretty well extended, and there's still a lot of line there.

Re: power assisted front disc brakes

If you are having your flex hose hit something, it is possible to put a little twist in the flex hose and cause it to curl. This distributes the flex over the length of hose and reduces the stress on the end crimp fittings. The most correct way to install flex brake hose is, "no twist". I only use a little twist to reroute the hose just a little.

Re: power assisted front disc brakes

I am currently looking at running my front brake hoses also. I am going to see if these adapters will work for this same situation.

Terrell,

This is what I came up with, it looks to fit good. Found the brake lines at Summit, 22” long with a 90 degree on one end to a banjo adapter.

Re: power assisted front disc brakes

Kevin, The Banjo adaptor you purchased was an3 to 10mm banjo? Was it the short version or extended?
