Could this be the cause of the leak? It has been in the car 10 months and what is confusing why is it only leaking from one particular calliper and that to a repeat of the issue. Could any further harm have been done by using the Brymbo dot4

Fortunately the first one I replaced was under warranty and so Is this one The brake system has Brembo dot 4 fluid It's definitely leaking from around the piston the rubber boot is wet and not the brake hose / the connection. As it is a repeat on the same side with the leak from the exact same component of the calliper I am wondering if there could be underlying issue isolated to purely the NSF? In general the car brakes exactly as it should

Hi folks Some advice needed around 10 months ago I accidentally pressed my brake pedal whilst my callipers were removed for q brake job resulting in the pistons being pushed out. Both front callipers were replaced and full brake system was manually bled. 10 months later I noticed the front drivers calliper was leaking from the piston. Replaced and now 3 weeks later the new one is also leaking. Anyone had this issue before / what could be the under lying issue causing the leak from one particular side.
