THATS OK SORTED.

btw the 1 inch ones are bm52

bm57 is the 1 1/16 aka z32

and the silvia ones have a 20% reduction and the skylines/z32 have a 40% reduction. the spring is interchangable but still a wast of time.

i went a gu patrol master. bm57(big one with no valve) as im using a adjustable proportioning valve. is better but not perfect. the rear calipers need bigger pistons to clamp harder (4x27mm) need to go 4x32mm)

all a waste of time so far. just a better pedal. im getting a proper pedal box cheap with masters and balance bar etc etc. (cheaper than rear calipers lol)

i think its the piston ratios that are not suited to a 50/50 split. for referance it fronts are 40.3/44.5 up from 38/44.rears 27/27

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
