If you're anything like me you like to go fast, vroom vroom. unfortunately we can't always go fast. think of it like this though, we have to slow down in order to speed up again! Yaaay! problem solved, except these brakes are shit and we're gonna need to deal with that. most brakes will tell you when something is array by feeling spongy or squealing as though its job isn't to slow you down but to break through the outer most part of your eardrum.
Before you dive into it use your eyeballs and inspect the area. we will be looking at severel components.

- check the rotor for deep grooves or a high gloss finish. if the rotor is deepley grooved, its time to take it in and get it turned, or buy new ones
- inspect all banjobolts and brass washers for leaks, this will cause air in to get into the fluid and cause the deadly "spongy" feeling in the lever. if they're leaky, order new ones, install and proceed to bleed the brakes
- remove brake caliper and examine the brake pad. make sure there is plenty of material left on it, also look for even ware on either side of the pads. remove pads and inspect the area for leaks and inspect the brake piston/pistons for grooves. once the pads are off put the caliper back on and make sure there is smooth movement of the caliper, no binding or restrictions.
Before slapping it all back on and going for a spin, take a second look, tighten everything to spec. then proceed to bleed the brakes. Because air can compress more than the hydraulic fluid in the lines, this step is crucial to having proper working brakes. we will go into more detail on that later.
