Yet, good for cuts ?

A couple of years back i was at a roadside mechanic and i cut my finger on a peice of glass. A rather deep cut and it was bleeding quite a lot. He promptly popped the hood of a nearby esteem, unscrewed the cap if the brake fluid reserviour and made me stick my finger in there. The bleeding stopped immediately! (im not sure if its a good thing or a bad thing , and have been trying to figure this out since then)

I'm pretty sure a doctor wouldn't have done that!

Years (ok, decades) back, a friend was driving us from London to Cornwall (about 300 miles). This meant quite a lot of hurried DIY maintenance the day before, including some new brake pads. He had to finish off by bleeding the brakes just before we left. Due to an accident, he squirted some in his eye.

He had swelling, pain and redness the whole day. I don't know how he drove, but he was the only one of the group licensed and insured to drive his car.

Brake fluid: nasty stuff. Except in brake systems, of course!

Brake fluid, very abrasive in nature. But I too have heard from mechanics about its efficacy in stopping bleeding and healing the wound. Though never tried.

Many years ago, one of those times when my mechanic who used to maintain the family Amby, was in good mood, would clean the carburettor by soaking it for an hour or so in the brake fluid and then cleaning with it. Dunno, whether it was psychological or something else,the start-up, pick-up and FE used to definitely show an improvement.

This Sunday, I found myself with a bottle full of DOT3 oil and some time.
The DOT3 was bought a couple of week’s back, but that day my mechanic's shed was closed.
I had been looking at the dot3 and thinking how to go about refilling my bikes disc oil.

I opened the main container and topped up the oil.
The brake was working fine.

The devil crept up my ear and kept reminding me that old oil is looking old.
Decided to bleed the brakes.

Opened the nipple cover and set up the spanner for the valve.
press brakes three times
HOLD
open and close the valve.
Repeat the above.

complete loss of pressure in the brakes.
spent more than 4 hours trying to get the air out.
The valve was spitting out oil as expected but still no pressure.

finally went to the mechanic, Monday morning.
took him half an hour to fix it.

what I was missing
the hydraulic pump, needs to be opened up.
springs et all removed, flooded with oil and closed.
voila the brakes work fine now.

What I learnt.
riding a bike without brakes is more fun.cheers:
