I retrofitted the 2001+ Stainless Brakelines ( Hoses ) to my 2000 Scrambler 2X4 this weekend to get rid of the rubber hoses.
Not an easy task.

Here are the Polaris Part #'s:
Master Cylinder to Brake Block # 1910501 $ 19.99
Brake Block to Left Front Caliper # 1910502 $ 26.99
Brake Block to Right Front Caliper # 1910503 $ 26.99
Brake Block to Rear Caliper # 1910504 $ 39.99

Here's where the fun begins:
The outlet on the MC on the 2001+ was changed from 1/8 NPT to 3/16 Inverted Flare. The line will screw in, but will not seal. The cure is an adapter from the NAPA Parts Store Weatherhead Part # 202X3. The fitting on the brake block ( located to the left of the steering stem )was the same. The brake block was also changed for 2001+ ( Part # 7052292, I didn't check prices ) and the differences are: the fittings for the LF and RF brakelines are 1/4 Inverted Flare on the 2000 down, and 3/16 IF on the 2001+. NAPA to the rescue again, with Weatherhead Part # 7818, 1/4 IF Male to 3/16 IF Female, You'll need two. Once the adapter fittings were installed, it all bolted together.
The brakeline from the brake block to the rear caliper is sold as a complete assembly, you get the hardline with the hose. The nut on the line to hose junction wouldn't come loose, so I changed both. Expect to take the front cab and air filter box off to get the hard line out.
I replaced the old brake fluid with DOT 4, and bled the system till all the air and old fluid was gone.
The brake lever had a firmer feel with more feedback on the test ride. It was a hassle, but it may turn out to be worthwhile.
I didn't change the rear pedal brake hose & lines as I didn't think the cost vs. improvement in feel was worth it.

Thanks for the info. I was thinking of up-grading the brakes on my Scram. Can you let me know how much better the brakes feel after your first good test ride? Do you think the improvement was worth it?

CaptNemo,

Hey, I could have told you that it wasn't easy. For some unknown reason Polaris decided to change to different fittings on their brake lines. It wasn't easy or fun, but I do like the better performance of the brakes.
