SAFE brake fluid level for pad/rotor change
'95 W124 E420...what is the "safe" brake fluid level to be pretty sure that none spills out/over when I do a front pad/rotor change? Also, after the pad/rotor change, should I simply pour back in the brake fluid I siphoned out, or get a brand new bottle of brake fluid from M-B parts shop and top it off? I just had my brake fluid changed less than 1000km ago during my maintenance...so the fluid is new...thanx for any info...
