    I know this sounds ridiculous, but it is an issue none the less. I bought this busted ms6 about a year ago. I finally got it to crank & replaced far more parts than I thought I'd have to. It's almost street ready and I bought new pads & rotors & installed them today.
    I only did the front after realizing I needed the special caliper tool to compress the rear. It went well. Super simple, I did take the 12m brake line off the caliper and decompressed it by hand / c clamp. When I put everything back on there was no compression. I did bleed both lines 3 separate times to rid the lines of air, but still no pressure.
    I did notice the 2 holes that are connected to my brake line, could it be those are not properly I'm alignment? It's the only thing I can think of, I have topped off my master cylinder and am just sitting here in my garage like an idiot with no brakes. Any insight would be helpful, thank you.
    All in all when I get everything working properly on this car I'll hit the next tier of issues to be fixed. Starting with Diamond motor mounts and new brake lines. ( Ohio life ) Just trying to get this ole girl on the road.

    You have to bleed all brake lines when removing a caliper. You probably still have air trapped in the system. Also when bleeding brakes you need to follow this procedure which is pretty basic for all cars unless specified by the repair manual.

    Bleed brakes from the further point away from the master cylinder working towards the front. I.E. RR, LR, RF, LF checking the fluid level and topping off between bleeding each location.

    What two holes are you talking about concerning the brake line? If you plan on replacing the brake lines or hoses now is the time to do it since you already need to bleed the system. If making lines from universal hard line spools then you really need to be sure of their ability to hold pressure after you flare them. If you do your own flaring I suggest disconnecting the battery and using a broom stick or other device to keep the brake pedal applied. Then check it over the course of a few hours for leaks. If you find any, repair the leak, rebleed the system and try again.

    Ooof. What L337 said, plus I'd recommend a picking up a power bleeder as it makes the job 99.9999% easier.

    So this might be an old thread but was bleeding my brakes and remembered this conversation in shout one day. Hope it helps someone to bleed their speed 6 brakes if they run into issues doing it the other way!

    I've always done it this way and my brakes have always felt great! :D
