Need help with vibrations

So I've been having this bad vibration when i hit the brakes, I thought it might be the rotor so I took it off and replaced 1 on the problem side, now it feels like it's on both sides but both rotors are perfectly fine, the shudder is still there and it's getting increasingly worse as time goes on, i know my truck is not equipped with ABS so what could possibly cause this shudder??

Any ideas are helpful and im willing to look at or test. I'm just trying to have my brakes work to 100% so I don't have to worry about them possibly failing!

Any help at all would be appreciated.

 

Most brake shops will diagnose and give a quote for free.

If you’ve found yourself stumped, that’s what I’d do.

 

Sounds like you might have a frozen piston or two in your caliper.

You can buy a kit to rebuild them from Toyota for about 25$ for both

 

How do you know your rotors are true? Did you check them for runout? New rotors can be warped right out of the box and need to be turned.
As Mr. Pink said you can have a stuck caliper piston or you could have dirty/sticking caliper guide pins.

 

Brakes 101, ALWAYS REPLACE THINGS IN PAIRS.

If it’s only when you hit the brakes and you feel the vibration/steering shake, you have warped rotors and/or drums. You need to replace the pads and rotors on BOTH sides and see how it drives. After that, you can move to the rear drums but I bet it’s the front rotors that are the culprit.

 

This.^^^^^^

You cannot tell if a rotor is warped or not by looking at it. You need to replace both rotors and pads on the front at the same time...and then the rear if that doesn't fix it. You can't mix and match brake parts.
