Could not find any info about e30 hydroblock. Because i have one and want to use it for my experimental project. Anyone got any related links? about how is it connected in its normal operation, electrical scheme, valves specs ................And I just recently found out - does it really have only 3 valves?? Left, right and rear... How does it operate then... because i thought 6 valves are needed (inlet/outlet for each channel) for abs operation
