everytime its cold out side like below 25 degress mijoraty off the time i hear a wierd whinning noise from my front brakes and also the brake peddal pushes out... when its warm outside the abs is perfectly fine. anyone knows what the problem might be?

 

on a cold day, does the problem go away once the brakes heat up?

 

yes it goes away but den itll come an go rarely if the btakes r warm

 

Do you mean it pulses or it's harder to push in? If it's harder to push in, replace the master cylinder.

Usually a whine from the brakes is the wear indicators telling you that it's time to change the pads.

 

What year is your car? Is the ABS light ever illuminated? Check the wheel speed sensors for dirt.

 

its a 94 n the original cluste and abs lights isnt on.... n it gives a quick hard pulse n then i hear like wierd noise coming from the front first the d.s. den p.s.

 

Sounds like a warped rotor. Could possibly be a sticking caliper. Does it pull to one side when it pulses?

 

Sometimes the high pressure reservoir leaks and the motor will run to repressurize it.
