		The proximity of the tubes doesn't concern me for two reasons: 
 
1/ Heat will tend to rise from the pipes, so only radiant heat is a factor, mitigated by airflow.  Note that the plastic-coated metal clamp still looks OK. 
 
2/ Hot fluid doesn't flow into the master cylinder except under rare conditions.  Namely, only after a major system leak has already occurred.  Otherwise the hot fluid stays over a foot away. 
 
Don't Worry.  Be Happy!
