Technical Ulysse front brake disc replacement

[niloctap]

Hi, any advice on easing the removal of the two 19mm bolts holding on the front brake calipers, in order to remove the disc? I've tried heating the caliper holder with needle jet blowlamp and using a nylon mallet on a 19mm ring spanner, but no movement. I knew I was in for trouble when I saw they were 19mm! Any advice gratefully received.

Might be worth buying a long bar with a 19mm socket or a 19mm wheel brace might work.

Have you tried some penetrating fluid?
