Hi everyone! Im about to change the master brake cylinder in my friend's 93 legend. I know how to take it off but can anyone tell me if it is necessary to bled the abs system or can I just disconnect the brake hoses from the master cyl without any problem? any feed back is appreciated! thanks!

I just did mine myself one month ago. It was a straight swap out. I did NOTHING with the ABS system. Make sure you adequately bench bleed master cylinder just b/4 installation. After instal, bleed all 4 lines at their brake calibers. Its very straight forward. About 2 hours. After instal, IF brake pedal goes to floor, first re-bleed all four lines, second take a hard look at your brake power booster upon which the master cylinder mounts to (big black round flat disc mounted to the firewall exterior underd the master cylinder - it works on engine vaccum and can have an internal leak which will also affect the idle of the engine); lastly you could have a leak at the ABS pump (oposite side and ITS EXPENSIVE!!!). Good luck!
