I put 91 si front brakes on my 1990 dx. Now am I gonna need the master cylinder as well. Here's the prob I drive my car around for like five maybe ten minutes during that whole time the front brakes seem to be gripping tighter an tighter as I drive along. tia

c'mon bump

 

The Si brakes are pretty much identical to DX brakes. There is maybe a caliper difference but its a minor one at best. Did you change the power brake booster? The Si and DX master cyl's are the same bore size(13/16) and you wont need to swap the 2. hth

 

did you do a bleed? but yeah i thought they were the same

 

awesome, yea I swapped the boosters as well as the MC simply because the kid that owned it before me had a new one put in.

 

yes
I did bleed
