Retrofitting Stainless Brakelines to Older Scramblers
#1
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.

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.
