Question brake light on dash.

i just put bmw ati front calipers on my 75 2.0. they look almost just like the old ones, but 50% bigger, or so.

it was pretty simple, i blead the brakes and put new ati blue fluid in the system.

i blead the system useing all 6 bleeder screws ,and even did it twice.

the brake light on the dash is on, and im not sure i have all the braking i should.

ive test drove the car and made several stops, even locking up the brakes a couple times to test the prop. ratio.

the front brakes lock up but not the rear.

and the peddle seems pretty soft.

i also already have a 19mm master.

Did you bleed the system until it was all blue coming out? Did you knock the wire off the M/C while you were working on it? Bleed the sytem again at all 4 corners and bleed the top ones after the lower ones.

You did not say if you replaced the prop valve? If you still have it, get rid of it as it is way off now due to the larger front calipers. As skline said make sure you got blue fluid fully from all 4 calipers. Does the 19mm m/c switch have a reset button, if so push it. Good luck

The 19mm one does have a brake warning switch, and that likely has a reset button on it. Find the button (often/usually covered by a rubber nipple) and press it.

Make sure the handbrake handle is down, as well.

You might try bleeding the proportioning valve, as well. Crack the fitting at the outlet (or are there two outlets? I can never remember!) while someone is holding the brake pedal down. Catch the brake fluid that comes out--it eats paint, which leads to Our Greatest Enemy. (Rust.)

yup dave was right again, it was the small reset button on the m/c warning switch. more like a small pin or nail though.

thanks
