Hi All

i have an issue with what I believe is sticking brakes. I have not determined which one but I believe front left. I have a couple of questions.

if it is stuck will I need to replace the caliper in its entirety or can it be “fixed”

if I do need to replace do I need to do both sides?
 

not really sure of the procedure to determine fault and fix but if any of you kind people can point me in the right direction I would really appreciate it.

Thanks in advance

Martin
