Mast Cylinder Front

[mhart]

I have a 99 Z71 NBS, Would someone tell me which line on the master cylinder is the front brakes?

Thanks

I don't know where you would get that information. It might say somewhere in a GM factory service manual or with installation instructions for a new master cylinder, but probably would just mention it in a diagram if at all. Or buried in the troubleshooting text in the factory service manual.

 

If you have a double fluid compartment master cylinder, I suppose you could try bleeding one of the front brakes a bit and see which compartment then has a lower fluid level. Then I would assume that the line under that compartment would be for that compartment?
