just installed all new break pads , its been about 3 weeks , I've notice when I break from slow speeds its fine but when in high speeds the break pedal hesistates for about a second then breaks. At times it feels really shaky when im breaking.I believe it might be an air bubble or I might need new rotors. I haven't really bother to break them in since I bought some that said no breaking in required lol. Should I bleed out the breaks? what do you guys think? id appreciate any input

 

personally i'd try bleeding them first and topping off the reservoir.

 

Try a proper bed-in procedure.

Cars have brakes. You break things.

 

air bubbles have absolutely nothing to do with noise

Anytime you do pads, you should bleed your brakes. Brake fluid is hygroscopic, meaning it absorbs water. Brake fluid is a maintenance item and should be done once a year for your typical car. But that is completely unrelated to your issue. Backing plates, anti squeal compound, proper bed in as suggested above. All of these should be part of the equation when doing a pad replacement, no matter what pads.

 

Remove your break pads and install the proper brake pads, it might help.

 

dunno why you would install broken pads to begin with, but wouldn't you expect noise from such things?

 

Sounds like you didnt do the bed-in procedure, like mentioned above. Did you?
