does anyone know what would be the cause for this? Depends on how I break, when i come to a complete stop, my car would jolt forward really quickly and back then do the normal jolt forward and back. I don't know if I'm explaning it correctly. Instead of doing the normal front and back when braking, it does it twice...

 

is it possible that your breaks are slipping. Is there any noise?

 

no...what does it mean by slipping? does it mean i need new brake pads?
