After Changing Head Gasket the handbreak light stays on why?

[tubery]

2 weeks ago i had my timing belt and head gasket changed of my 2000 Peugeot 206 as it was suffering from oil leak.

Now the handbrake lights and oil light is flickering when stopping in traffic and like usual i have the handbrake light lit i have my handbrake on so i want to know if chnangin of the Head Gasket changing has got anything to do with this.

The break light is also flickering

Have you checked the brake fluid level and engine oil level if it is up to the mark?
