Hello,

Yes, this is a common problem it means the master cylinder push rod is adjusted out too far cause the master to not fully release and building pressure in the system. To confirm this is the problem loosen the master cylinder mounting bolts three turns and the brake should release. If so, remove the master or just move it forward and adjust the rod inward about an 1/8 inch or 3mm.

Let us know what happens and please upload pictures or videos of the problem.

Cheers, Ken

When the front brakes lock up can you loosen the nuts that mount the master cylinder to see if the front wheels start rolling again? If not you need to replace the brake flex hoses.
