i just bought my first volvo. i am liking it right now. but i bought it with a brake problem. The seller was one of my friends and got it cheap. When i go to brake the brake pedal starts to act up and move. mostly going up and down. it doesnt madder what speed am going in the car when i brake it seems to do it equal. Anyone have a clue what it could be.. i was think something to do with ABS sensors or a bad caliper.

 

Hi and welcome to the forum.

I think you are likely correct. Do you have a CEL?

 

which one do u think it might be?? and what is CEL?

 

Cel is your Check Engine Light

 

ABS Module.
