1994 f53 460 Brakes Issue

[Billw94f53]

Ok guys I need some help
I just replaced the master cylinder on my 94 f53. My son in law was going to surprise me by bleeding the brakes but he took the rubber hoses off the front brakes instead of using the bleeder. Now the front wheels are locked up but if I open the bleeder valve with no brake pedal pressure the wheel will turn but as soon as the brakes are applied and released the wheels will be locked up again.could it be the rubber hose problem or do I need to check other items. Thank you for any advice

The master cylinder will hold the brakes on if it does not completely return, after stepping on it. That's the first place to look.
If there was a rod between the master and the booster, it needs to be set correctly.

Second place is to check if the master cylinder has a check valve in it. Back when drum brakes were used, master cylinders held some pressure to the drum brakes.
Disk brakes don't need that and will hold if its in the master. The check valves are in the ports, where the lines connect and most can be pulled out with a sheet metal screw.

So I had this sticking brakes after replacing the master cylinder I checked everything and come to find out I used the new fitting that came with the master cylinder on the front brake line port and I found out after checking the old reducer that the new one did not let the fluid flow back after releasing the brake pedal so I put the old one on and problem fixed
