what car? and year?and does the brake go to floor or is the pedal hard to push. sounds like you have a broken vacuum line or hose which helps engine run and also helps with brakes.

i saw you have a 2000 clk 320. look under the hood at the brake booster, driver side below windshield. there is a big black plastic hose that goes into the booster check that and also check the other end of that hose.

What happened. this all happened at the same time?? did you have it at a shop recently?? if you hear a hissing that is probably your trouble. what brake issues are you having??

anything is possible, but for the one wrench service you usually dont do anything major unless they upsold you some work. sometimes if they do a mass air sensor or spark plugs maybe they were in that area and broke something.. maybe you could have bad motor mounts and that is causing the engine to move too much resulting in a broken hose. but that hose just shouldnt break by itself.
