Chocks and brakes

[CROUCHY]

I recently had to get my Chimaera's front brakes fixed as they were sticking. I'm wondering whether it was because I had left the handbrake on whilst the car was garaged (for several weeks I'm afraid).
Should I buy some chocks and leave the brake off (my garage has a small incline).
If so, what sort should I buy and where would I get them?
Thanks.

handbrake only affects rear brakes,
but if the car is to be laid up then certainly leave off the handbrake and chock a wheel,
a house brick is more than sufficient or a block of wood will do!
