I bought this part last summer and never had the chance to replace the original until now. Usually I post in detail about the process but this is a relatively easy swap. Enjoy the photos.

These steel braided hoses are amazing. I can’t wait to get my new master cylinder in and test the front brakes.

I plugged it right into the original master cylinder for now. I’m getting a modern radial master cylinder to replace it. The banjo bolt is a little rusted but still works like a charm.

Lower hose.

Slick.

New pads, new steel hoses, and a new master cylinder on its way. Slowly but surely the front end is looking good. I’ll get new forks and bars this winter after the riding season.

Here we go:

This is my only method for draining the brake fluid since my bleeder screw broke off last summer. I had to remove the metal brake line that connects to the outer caliper, stick it in a plastic bottle, and squeeze the brake lever till it all squirted out.

The outer caliper looks pretty rough. You can see the busted bleeder screw in this pic. This was easy enough to remove, just unscrew the two bolts.

Yuck, crusty and caked on filth. These bolts can’t be salvaged.

I think I’m going to barf.
Notice the brake pad is next to nothing. I feel embarrassed that I was riding it like this for so long and didn’t notice.

The original paint is long gone.

Here is a shot after about a minutes worth of sanding.

Here is a shot after I removed the lower brake hose.

The lower hose is also not salvageable.

At this point it doesn’t matter but the metal brake line is never coming off that rubber hose, its stripped to hell and frozen solid.

I’m re-using the banjo bolts even though they look a bit rusty and old, purchasing a new set would be too expensive.

While I was down there I removed this metal tab that I assume is supposed to hold down cables or hoses.

Much cleaner.

Yuck. The upper hose and banjo bolt are fairly rotten. I should have replace these last year. My suspicion is the rubber housing that sits over the shoulder of the banjo bolt locked in moisture over the years and caused the extreme oxidation. I don’t plan on using the rubber insert when I install my steel braided hoses.

My master cylinder is great physical condition but I may get a modern one or at least one that is built for inclined bars and has a sloped reservoir.

Here is the last banjo bolt on for the upper hose that connects to the pressure switch that activates the brake light. I thought about removing the switch to clean things up but that would mean I would need one long steel braided hose that runs from the master cylinder to the front brake and its too late for that, I’ve already purchased hoses that replace my existing ones.

Garbage. So far, every time I pull a part off I’ve been able to sell it but not this time, these pieces are beyond repair.

Two bolts and outer caliper brake pad.

For the sake of page loading time, I’ll cut this post in half and continue on the next one.

Okay… no big deal, right? I was going to replace the bleed screw with the speed bleeder anyway. So I grab a pair of pliers and attempt to squeeze and turn.

Nothing. It wouldn’t come out.

So I try some vise grips.

Nothing.

Tonight I’ll to try one more thing. Use my dremel to cut a slot on the top of the screw and then a flat head screwdriver to try to remove it.

My Friday morning, as it turns out, was a complete waste. After I was unable to bleed the brakes I decided to remove the brake line and replace it with a shiny new one I ordered a while back.

No luck.

The brake line was frozen in the lower brake hose. I tried turning it with everything I had.

Until…

Cheap chinese tools.

I’ll just purchase a new lower brake hose.
