So, i just replaced my front brake pads last weekend and i noticed tonight that when i barely even press on the brake pedal a vibration occurs. This is around 30mph. Its not very agressive but deffinatly noticable. Any ideas why?? It has a pretty good leak on the rear drum brake cylinder.

 

First, fix the leak on the rear.

The vibration is most likely from warped rotors.

 

+1, new rotors or have the old one's turned/cut.

 

Fix the known probs first, then lets talk. You need new brake shoes and obviously at least one WC.

 

Okay. I am probabaly going to fix the cylinder sometime soon and with it not working, neither are the rear brakes. And this saddens me because i had a wheel bearing go out in like November and it destroyed the passenger side rotor.. lol So there is a new one on there. The previous brake pads had dug grooves into the new rotor but not too bad.

 

Always replace brake components in pairs. If you replaced one side due to damage, you should have replaced the other as well, and the pads at the same time.

 

I replace pads together but I see no reason to replace both rotors unless they're both bad

 

As you wish.
