Hello, I have a 90 crx HF with my front calipers upgraded to CRX DX calipers. I installed new Hawk HP+ pads and noticed under hard braking that the car dives to the right. I noticed on the pads that there was more brake wear on the right caliper. I replaced to brand new calipers, and a brand new master cylinder and I still have the same problem.

My next guess is that the 1725 proportioning valve that i have is bad, do you think my guess is correct? Thanks

 

I would check your suspension and wheel alignment first then replace the flexible brake lines.

 

i wouldnt think the prop valve would be bad as a first thought.

"upgraded DX calipers", what was the condition of those? did you look at the piston for crud or were they bought reconditioned? did you grease the sliders?

old brake lines is also a good guess too. check for blisters that will rob the caliper of pressure.
