Master Cylinder Question

[RMassa187]

Anyone know how to identify which circuit is front and rear on a master cylinder? I'm putting a 98 and up master on my first gen to clear a S/C. I took the master and combo valve off a 2000 S10. I don't know which side of the combo valve feeds that front and which does the rear. The lines from the combo valve went to the ABS modulator. Also both lines that feed the combo valve and the modulator were the same diameter. Something tells me the front may be that back and the back the front. Anyone??

They're not set up to be just front or back. They're set up to be left front & rear right & right front & rear left so you always have stopping power, front & back.

RWD vehicles are typically front to back biased. FWD are diagonally split. Thats not the case here?? 1st gen's are front and rear bised.

I'm pretty sure car manufacturers stopped making just front/rear biased braking systems in the 80s because of saftey issues.

1st Gen's had it til 93 in trucks and 94 in Blazer. So thats why I'm lost with this one
