Because I can't face replacing the front pads and fluid because it's 120 degs in the garage.  . It'll have wait for the weekend when it'll be a little cooler and I can do the job in the morning. I did get dumb lucky at the parts store. Kid wanted me to buy DOT 5 brake fluid and I couldn't remember WHAT the manual say so I skipped it and checked when I got home, DOT 4. Glad I didn't buy the fancy pants stuff he wanted me to as I read it can be a problem if the system's not designed for it. Al gave me a couple of ideas on changing the fluid so I hit CVS and got a oral syringe to pull out all the old fluid I can from the master cylinder but for I start pumping out the old stuff and adding new. Be nice to have the Bike back 100% ready to go again. (One thing after another this year) | ||

you can use 5.1 which is specifically formulated to be compatible with 4 | ||

I often dont ride much during summer cause I get tired of being so sweaty when I get somewhere. And regarding the DOT5 - the caps on the resevoirs on my S3 both say DOT5.....but manual says DOT4. Odd. I run 4. | ||

I second this, my local shop put it in during my oil change, I almost flipped the bike at the first stop sign. I am in love!  | ||

Hate the hot stuff too. Hate it worse when I meander north and the weather follows...ergh i'm melting. Stay cool y'all. | ||

It will have to be hot. Let me know when the heat gets here. Where can I get some of that magic Motul RBF600. | ||

DOT 5 is silicone. It should make a great brake fluid because it won't absorb moisture from the air. Silicone (by itself) has NO effect on rubber parts and therefore should be 100% safe. In practice however, this is not true. Conventional (DOT 3 or DOT 4) brake fluid, causes the seals in the master cylinder and brake cylinders to "swell" slightly, which is actually a good thing. This helps make up for wear. In order to have a similar effect, manufacturer's add something to the silicone in DOT 5 brake fluid to do the same thing. The problem is, it seems to be TOO potent and can cause the seals to blow out or hoses to fail if they haven't been designed for it. I used to see this discussion a lot in antique car magazines and forums. Guys would put DOT 5 in vintage cars hoping to avoid the moisture problems with conventional fluid which eventually lead to rust in the brake cylinders which cuts the seals to shreds leading to massive leakage. A short while later, some would get total system failure. The arguments would go just like synthetic oil arguments- "It's the best stuff ever!", "It ruined my brakes!", etc. I finally read a letter response in a car magazine (Road & Track maybe?) that explained the deal with the additives in the silicone in DOT 5 fluid. They weren't aware of the issue until they researched it. Bottom line- if you're system doesn't specify it, don't use DOT 5. (Message edited by Hughlysses on July 21, 2011) | ||

Plenty of info on badweb, old threads. DOT 5 is a Harley and tube-framed Buell spec. Bottom line: use what is spec'd for your bike. Do not mix 4 and 5. Do not empty, flush, and switch over to something not spec'd for your bike. 5.1 is compatible with 3 and 4 and not with 5; but why bother, and end up confused. | ||

I was under the impression that's why it is a bad brake fluid. When moisture gets into the system, instead of being dissolved into the brake fluid (kinda bad), it stays somewhere as bubble of water (worse). | ||

Bill- yes, I believe that did turn out to be a downside instead of a benefit for silicone. Water that does get into the system tends to pool at the low points, like the disk calipers or wheel cylinders. | ||

DOT 5 also doesn't eat paint. | ||

On the bright side, you don't have to shovel your driveway free of heat.  R | ||
| Mountainstorm |
I would gladly shovel the heat if it had any effect...my shop feels like a convection oven. I had this idea I was going to tinker on the bike...right up till I opened the front door...it was like taking a peek at a pizza. Hence me trolling instead of puttering. | ||

Does any one have the plans to build a water mist system for a patio? | ||
| Britchri10 |
No plans but they are fairly common in this neck of the woods. They seem to run in a similar fashion to ground sprinklers but use something like 1/4 inch PVC pipe & diffuser heads. We use a couple of portable units to "mist" supporters at our Rugby League games. The portable ones have large (about 12in diameter) fans that blow the mist over the people. It can reach an area of about 10 x 5sq yards in this way. Chris C | ||
| Cowboy |
Chris the only ones I have looked at were very small and expiencive. I think I could build one much cheaper and large enough to cool a 20 X 40 patio. would be nice for August B B Q. I am still fooking for some drawing ---TKS | ||

Cowboy - I see you are located in 'Loozyanna'. I'm thinking any kind of water mist system in that near 100% humidity might just end up spraying hot water down your sweat-soaked neck. I'm under the impression that they only cool the area if the relative humidity is really low. It's the evaporation that does the cooling. You need dry air like they have here in the southwest.

I'll have a word with the guys who provide the portable "misters" for our games & see what they say. There is no game this weekend but I will catch up to them as soon as I can & post up any results. Chris C | ||

Cowboy: Take a look at this site http://www.mistcooling.com/doit_yourself.htm It may give you some ideas & it works off household pressure water. Chris C | ||
| Cowboy |
i looked at one at a yard sale and it worked realy well but it was in a cover and owner would not let me take it apart to check it out. HE HE HE | ||
| Cowboy |
Tks a lot Chris that is the very thing I am looking for. TKS--TKS. | ||

Disney World uses cleverly disguised misters hidden in shady vine covered trellis "coves" when it gets hot.. Shade plus a fine mist is the best you can do this side of A/C...Disney also uses A/C units designed to recirculate a lot of the air....you put the air supply vents in a perimeter all around the area, with the return in the center...we have a similar setup in our shop... | ||

for the home units i'd add some extra flexible line to the system that could be coiled up into a container of salty ice... | ||

Salty Ice in a cooler with the flexi-hose coiled in it is one of the easiest & most effective ways of "chilling" tap water that I know of. It's a poor man's heat exchanger. Chris C | ||

When I lived in Indianapolis, I would feed a garden hose into the inlet on a leaf blower. Neighborhood kids loved it. | ||

Bottom line: use what is spec'd for your bike. Do not mix 4 and 5. Do not empty, flush, and switch over to something not spec'd for your bike. That sums it up as far as DOT 5 is concerned. When moisture gets into the system, instead of being dissolved into the brake fluid (kinda bad), it stays somewhere as bubble of water (worse). Then when your brakes heat up, the water boils, turns to steam, and your brakes get spongy. |
