Super six-pots!

-

Unwrapping the March edition of CMM I couldn’t believe the article ‘Super-sixes or pish-pots’, which I’m convinced was written for me! Back in December 2017 I purchased a 2000 Kawasaki ZX-7R, which came with non-stock Nissin four-pots. Being non-stock and after discoverin­g that I was unable to remove the calipers without having to remove the front wheel and brake discs, in February I decided to change them for fully refurbishe­d Tokico six-pots supplied by Powerhouse; and as your article rightly states, ‘the brake caliper experts’. So, armed with fully refurbishe­d calipers and new Venhill hoses and aware that these calipers have a reputation for trapping air when bleeding I opted for reverse bleeding, a method that forces air upwards as nature intended. To date, I haven’t completed many miles with the Tokicos but I’m very impressed with them so far. Unaware of the Facebook debate (what’s Facebook?), here is my two-penny worth: anyone who has developed a product for commercial release appreciate­s the endless testing that the product is subjected to. I can only imagine that the six-pots were tested to death by the Tokico engineers and only signed off once fully happy with the design. As a result, I wonder if there is a case of a bad gardener blaming their tools for those that believe there is something inherently wrong with Tokico six-pot calipers. Graham Seed Bertie says: “Glad you like the article, Graham! More ‘Big Questions’ on their way soon!”
