I have a 94 CBR 1000F. I would like some input on those who have de-linked their brakes. I want to put stainless lines on, but replacing the whole linked system is cost-prohibitive. Any hints on the de-linking proceedure? Are (front) dual racer lines street legal...will they pass a (Texas) saftey inspection? The rear brake and clutch are a no-brainer.

 

I can only report on what a mate done with a Blackbird but I can't see it being any different for the thou.

1. A billet piece of alloy is needed on the left fork the goes from the caliper to where the DCBS piston bracket bolts on higher onto the fork.

2. All 3 callipers need to have a hole drilled so the all 3 piston are joined hydraylicy and a bolt put where the brake line used to feed into the middle piston.

3. throw away all brake lines.

4. Put a new line from the rear master cyl to the rear caliper.

5. At the front my mate didn't use the original master cyl. He used a radial cyl with a seperate line to each of the front calipers. I dunno if the stock one will do, but I can't see why not.

As for legailty of using braided lines I can't comment as I'm from Australia, but over here normal braided ones aren't legal for road use. The braided lines need to be covered with some kind of plastic coating to make them legal. Plus they need to be flexible.

 

I'm in the process of doing this now. I'm waiting on the brake lines and will post pictures of the process soon.

 

What one learns on the forum is interesting. I never gave a thought to legality when replacing the stock brake lines on my CB650 with braided lines. Oh well. It stops a whole lot better now. Why would the authorities care if brakes are upgraded anyway?

 

The goverment cares, because the "off road" marked equipment has not been tested for the conditions of "every day driving".
Racing conditions, even though they are very harsh, is only for few minutes/ hours or few races, then it gets replaced.
God forbids you have an accident due to brake failure and it is found by your insurance company, they can deny coverage for using "non DOT" equipment/parts on your bike.
You can also have a problem with the DOT for breaking the law by using "non DOT" approved brake lines on public roads.
If you had a mechanic do these, he can also have problems and be liabel for installing "non DOT" parts on a vehicle for public roads.
So, all liability from any accident can fall upon you, even if you didn't cause the accident.
This info I got from a Lawyer, that races Auto-X here in Texas, so I pass it on to you at cost.
I do believe that the Russels and/or the Goodridge are DOT, but I don't know about the Galfers.
Good luck.

 

I'm happy to report the operation was a success. The front and rear brakes are independent of each other and the lever/pedal feel is solid. Now I can trail brake.

After removing the mass of hoses and brackets I used two pieces of 1/8" aluminum flat stock 2"x 3" in size to make a bracket to replace the secondary master cylinder on the left front fork leg. Using the removed steel bracket as a pattern, I marked my holes and headed to the drill press. After scrounging up some aluminum spacers a longer bolt and two flat washers I was in business. Next I removed the center piston from all three calipers and located where the fluid passage was in relation to the piston bore and used a 3/16" drill to open the passage. Next I removed the other two pistons from each caliper and cleaned them out and reassembled them. I used three short 10x1.25mm bolts with sealing washers under them to plug the second brake hose attachment on each caliper. Finally, I installed a set of braided stainless steel lines for a 1991 CBR1000F and bled the brake system.

 

Did you use a double racer line (2 lines directly from the master cylinder) or one line off the master cylinder which goes into 2 lines above the front wheel? Your pics look great...clean job!

 

Yes, I did use a double line set-up and the lines came from... http://www.helusa.com/
Nice kit, and everything needed was there. Their distributor is located in FL so I got them the next day.

So far I've put about 300 miles on them and they're working great.
Thanks for the compliment on the install.
