    All over out little bikes are great in every area, but in all the reviews I see, the brakes come in for some real criticism. What is the best way to fix this?
    Would a simple combination of braided lines and sintered pads work? Are the wavy discs worth it? What about master cylinder upgrades?

    Wavy rotors are a fashion accessory that reduce the swept area. In other words it is like fitting smaller discs. They had a purpose on dirt bikes to help clear dirt and mud.
    A serious upgrade is to fit 4 piston calipers.

    Avoid chinese pads and discs.

    Almost all jap bike manuals call for replacement brake lines every 4 years (for rubber lines) - no one ever does it. So braided brake lines are a good idea.

    Keep the brake fluid fresh - every 2 years at minimum.

    Service your calipers with soapy water, scrubbing, pumping the pistons out and scrubbing them, retracting them, and repeat, until they all come out evenly.

    Braided lines help & I use organic pads on my street/drag bikes and sintered on track bikes. Wavy rotors...what @maelstrom said. I have them on my drag bike only because that's all I could get at short notice!

    My FZR still has the original setup .... all I have ever done is replace pads and fluid over time as mentioned above and deglaze the original rotors with a wet steelo soap pad and bed in the pads when new ..... I have never had any problem stopping and I never use the rear brake ever

    What bikes have been 'crticised' for their brakes? ..... of course anything can be updated or improved but Ive never heard anyone complain about the twin disc setup on the old inline 4s if maintained correctly :)

    @GreyImport The FZR has 4 spot calipers and the ZXR has the scooter brakes.

    Yep. It almost seems back to front. The ZXR has USD forks (with scooter brakes) and the FZR and GSXR have normal forks with great brakes!

    The figures I have for the ZXR250 show the caliper mount C-C (pitch) as 45mm. If that is wrong please let me know.

    If it correct then it will need an adapter bracket. The ZXR400 uses Tokico's with a 62mm pitch.
