One more data point:

Hawk HPS pads have come up a couple times upthread.

Yesterday I swapped in HPS front pads on 3014, which has the GM front brakes and Jag IRS. After bedding in the new pads, I found a noticeable improvement in bite and an easier time probing the lockup threshold as compared with the Centric pads that came with the kit. I may need to add some more front bias now.

If you're getting too much bite (line pressure) on the front, shift the balance bar shims so that the bar free length is increased on the side toward the front master. On the next release of the manuals, I'll illustrate that more clearly.

Bob , quick question . On your attachment on the bias bar setting , you say to set the front rod approx. 3/8" longer than the rear .
In the ERA manual I have for ERA 757 , it says to set the front brake cyl rod 3/4" thread to lock nut backside and rear brake rod to 1/2" thread to back of lock nut , which is 1/4" longer for the front brake link .
If this is a change , would it apply to my car ?

Thanks
