lol im the same way. But i guess its totally acceptable to just bleed through the system. My instructors never really pointed out any other more effective means of bleeding brake fluid besides using a vacuum box.

After replacing the calipers everything seems to be working normal again...

Did replacing your calipers solve the problem? If so was it temporary? What brought your attention to the master cylinder?

Somewhat yeah it wasnt sticking as much till i notice at home on my street its a little up hill when i parallel park to reverse i usually just put my foot on clutch and use the down hill momentum to back up, i notice its not as fast as its use to be, its like i have my parking brake on half way something is still holding it back, not noticable when fast or normal driving but got me thinking i changed almost all the major brake parts plus i rebleed the lines when i changed brake fluid so may as well change the master cylinder and fix ever since.

I hope everything turns out for the better this time around OP, and no more calipers breaking on you.

A lot of people say its ok for a street car, but iv seen plenty of brake failure of Daily driven cars due to that fluid.

Its not a bad fluid by all means, its awesome. But its use on regular street where you don't get up to good temps in the brake lines may cause wear.

I wonder if even your calipers are broken at all with that fluid still inline. I suggest bleed the brakes and switch to a DOT3/DOT4 fluid, and not a racing fluid.

But if you believe that the fluid is not the cause, then ignore my post.

The car in your signature! which car is it?
