E clip or circlip

[Daniel1312@aol.com]

Hi List,

On the rear brakes the slave cylinder is held in position by a stupid clip 
called an E clip.  When I ran standard rear brakes I replaced the E clip with 
a circlip which I found was much easier to fit.

However, I seem to recall that there is some argument against using a circlip 
instead of an E clip - something to do with allowing a degree of 'float' or 
'freeplay' of the slave.  Anyone know anymore about this?
