Bleeding brakes with dual discs

SOURCE: Soft front brakes after bleeding the brake lines,

One easy thing to try is clamp the front brake lever overnight. If there are any air bubbles in the system they should be compressed and in theory work their way to the highest point in the system - the master cylinder. Doesn't always work but the price is right.
My experience has been air enters the calipers more than it does the master cylinder due to miscommunication between the person squeezing the lever and the person opening the bleed screw. They do have bleed kits these days that make it a little easier.

your rotor(s) are bent so when you bleed the brakes everything is good but when your riding the bent rotor is pushing the the caliper pistons back and when you go to brake you have to pump them up take rotors off and inspect them

gravity bleed. make sure fluid is always full. crack open the bleeder screw and let the brake fluid drip until no bubbles. Then close bleeder top off fluid and replace cap. Now, pull the brake handle. If there is no pressure or has bleed down, the master cylinder is kaput.

Squeeze brake lever or depress brake pedal with mild force and hold pressure as you loosen bleed nipple (small dome shaped nut with tiny hole in centre) slightly to allow trapped air/water to spray out. maintain pressure till an uninterrupted flow of clean brake fluid is emitted, tighten up bleed nipple and replenish hydraulic reservior with NEW fluid. Test before hitting the tracks. Cheers.
