I was checking through the FSM and owners manual and found nothing on the brake fluid capacity. I will be rebuilding the front brakes soon and trying to figure if I have enough on the shelf for the task. So what is the capacity of both front and back brakes?

 

About an egg-cup each! Make that a couple each, allowing for flushing out the old fluid until the clean stuff flows. I have two bikes that use DOT4 fluid, so blew out on a fresh 1 litre bottle so I could service them both - I still have more than half of it left! A litre is pretty close to a US quart, so for your brakes you can probably get by with around half a pint.

 

I have an 11 fl oz bottle hope that is enough just for front end.

 

That's almost 3/4 of a pint, so should be more than enough!

 

Btw I need to flush the brakes after rebuild. Someone mentioned using denatured alcohol but was wondering if rubbing alcohol would work.

 

If you do that you'll need to flush through with brake fluid, to clear out the alcohol, so why not just use brake fluid instead? I've never felt the need to do anything else.

 

I'd just use the DOT fluid to flush. But, if you must use alcohol to dry everything out, then use rubbing (isopropyl) alcohol. Don't use that "70%" garbage as the other 30% is water. You don't want water in your braking systems. Isopropyl 99% is much purer.
Good luck with your flushing.

 

All in know Graham is the po mixed dot 5 and 3 together and it crystalized causing the brake failure in the first place. I bet anything there's dot 3 in rear brakes. I wanted to make sure nothing mixes in rear and the front is cleaned out of any contamination from the damage that mixing the 2 brake fluid had caused.

 

90% work? I can get it cheap. I'm not sure if I can find 99% in this podunk town.

 

I understand! I'm guilty of doing that very thing myself in the past, in complete ignorance, resulting in damage to all major parts of both braking systems and an expensive rebuild. Personally I'd strip to clean, then rebuild with new rubber parts. Be sure to check the internals of the master cylinders, as I found deep erosion in both of the main cylinders where the piston operates. Imminent failure IMHO! Also consider replacing the brake lines - I used braided hoses.
