The Answer is no.
The idler pulley has nothing to do with the brakes. If the idler pulley is bad it could throw or break a belt, and then your engine will stop.
Is it serious if my car idler is making a noise?
Most idler pulley's are near the top and usually quite easy to get to. Press on the belt somewhere, enough to deflect it a couple inches and watch to see which pully is mounted on a tension spring. That is the idler pulley.
The idler pulley is mounted on a plate that needs to be removed. In order to remove the plate with the idler pulley, you must remove the engine mount to get out the idler pulley. To remove the engine mount, you need to jack-up the engine from the bottom of the oil pan (Note: place a piece of wood plank between the bottom of the oil pan and the jack).

The idler pulley is located just under the A/C compressor. There is a bolts in the middle of the pulley that needs to be removed and the idler pulley can be removed. Sometimes these bolts stick and my need to be pryed off. You may also want to removed the radiator fans cow to give you some extra room.
If your car has a serpentine belt it will have a tensioner pulley. A tensioner pulley is easy to spot. All of your bolt on accessories i.e. water pump, alternator, a/c compressor etc. will have a pulley to run each one. There will be 2 other types of pulleys, a idler pulley and a tensioner. The idler pulley will be a single stationary pulley with a bolt going through the middle and the tensioner pulley will be on a spring loaded piviot.
Probably not usually. For an idler pulley to put so much drag on the belt system that it stalls the engine, it would break or throw the belt altogether before the engine could actually stall.
The A/C belt uses an idler pulley accessed from under the car. That lock nut is in the center of the pulley, and the ajustment bolt is located on the side of the pulley.
If an idler pulley is broken, I would advise not to drive it anywhere. It would effect the power steering, water pump, alternator and coolant fan causing you to get stuck on the road and possibly cost many more $$ in damage.
It sounds like you either did not get the belt on a pulley all the way or the idler pulley is frozen up. Take the belt off and make sure the idler, or tensioner pulley, turns freely. Reinstall the belt and make sure you have it on all of the pulleys correctly.
It could mean the beginning of the end for your belt or the idler pulley, have them both checked out.
You might check the idler pulley. My car is in the shop right now...thought it was the timing belt, but it turns out the idler pulley was the actual problem. Hope this helps.TimingI believe that's an interference engine so being off on the timing just a smidge will prevent the car from running
