But on there they have actual mechanical engineers that have studied fluid transfer, on here we have people that assume what it would do.
He does not claim in his post he studied fluid transfer and they are wondering why GM used a 1/4 line to the back which to me is obvious. The 1/4" line feeds 2 3/16 lines to the wheel cylinders or disks so the added volume is needed. The actual engineers who designed the brake system on these cars did study all about hydraulic fluids and tested the system. But then again you can believe what you want.
