hi all, i hade my master cylinder changed last week at a grarge, the brakes are loads better, but today i needed to stop quite quick and slammed on the brakes, i dont think the abs cut in as my front wheel nearly locked up, and i dint fell any push back of the peddel, ive scaned with vagcom no faults in abs, does the abs need resetting after changing the m/c? should there be push back off the peddle when barking hard? the brakes feel ok when barkng normal. thanks in advance
