I just recently did a 5-lug conversion on my DB8 but I'm having a problem getting my brakes to work properly. I had my brakes bled for me but my brake pedal is still going more than half way down to the floor. Please help me! Let me know if you have any suggestions of what I can try. My brake master cylinder was perfectly fine before the conversion and now I'm being told that the cylinder might be the problem. But I just don't see how it could go bad in only a few days. Thanks...

itr brakes have a bigger resoivour for the brake fluid.. so you might need to bleed it alot more..
and check to make sure fluids are top and you have no air.
there is a likely hood that your MC just so happened to clunk on you while you did your swap..
but anyways good luck.

 

Thanks. When I had my brakes bled they guy told me that he did it 3 times and that didn't help either and I called an Acura dealership and he looked up the part # for a GSR and Type R brake master cylinder and told me that they use the same one/same size. He also told me that the brakes are the same size. So, I don't know what to try next. But thanks for the reply and suggestion...

 

The MC is the same, but the brakes aren't. You gotta bled it more than 3 times.

 

front itr brake calipers are larger diameters
so you definitely have to bleed it more.

-> and thanks blueintegraboy didn't know that they were the same MC.

 

Bleed it again. It only took me one try to get everything correct

 

bleed them alot, when you change lines/ex.....you have to bleed all four corners at least 2times and then try........even then you might have to fill and bleed again. Nothing shitt'er then a soft brake pedal!

 

Bleed your master cylinder first, then each caliper.

 

How do I bleed the master cylinder?

The same way you bleed your caliper. What you need to do is get a buddy to pump up the brakes. When he is holding the brake pedal in, loosen the fitting (brake line) that is closest to the firewall first. When you loosen it, it will let air escape and let a little fluid drip on the ground. It may get a tad messy but thats how you do it. Once you do that process with the front fitting a few times, do it to the 2nd fitting (the one furthest away from the firewall).

After this is all done, bleed each caliper.

 

make sure you clean up your brake fluid if you're bleeding the mc, it will eat up your paint/body.

 

Thanks a lot guys for your help and input. I bled the lines again w/my cousin and my brakes are working better than before.
