Ok so I have a 90 xj and every time I step on the brakes there is a buzzing noise coming from what sounds like under the hood, passenger side. Anyone herd of this? Or have this problem. Brakes work fine. HELP. Driving me crazy. Thanks

 

What do you mean by "buzzing" noise? and is there any vibrations?

 

that'll be your abs pump. it's normal for that abs system.

unless, of course, you don't have abs, then i'd say it's weird.

 

Every time it's suppose to do that. Weird man, any way to fix it?

 

No vibrations just noise. Last about 2-4 seconds.

 

yup, they do it all the time. some are louder than others.
