    Hi I’m just looking for some help I installed my chase bay hydro onto dual caliper (brembos 4 piston) a few days ago and it has pressure on the Handle and locks when the tires are in the air but once I’m in motion driving around it doesn’t I tried to initiate a drift it doesn’t lock it keeps on spinning slowing the car down(yes I’m putting the clutch down when pulling it) any tips on how to make it work? Checked all lines to made sure (they are tight and no leak) also went through a bottle of dot 4 fluid bleeding them and still no change .

    What happens if you apply slight brake pressure to the main pedal?

    Assume you've plumbed it in-line, not a dual-caliper setup?

    Had a friend pulling on the hydro 3 times and hold it down. Then i open inner brembo bleeder screw and repeat the process for the outside bleeder screw as he holds it down.

    Try bleeding with the caliper bleed valve higher than the cylinder. Air can travel to the "Highest" point of the system and stay there. Failing that, check seals aren't worn on hydro cylinder.
