So this weekend I installed my drilled/slotted rotors from brakeperformance.com and I ordered all new stock pads from infinitipartsusa.com. This was my first time installing rotors on the G so I used the service manual and it wasn't too bad. Everything was installed fine but I noticed that my pedal is WAY softer. The car stops fine but I have to push the pedal way farther than I did with the old pads. The pads looked identical except the new pads had the metal noise thingy and the old pads didn't. I have no idea what the problem could be.

 

It sounds like you might need to bleed the brakes. I'm no car expert by any means but I have heard of air getting into brake lines causing softer pedal. Did you change the calipers with the rotors and pads?

 

That's what I was thinking but I'm not sure. In order to install rotors you do have to disconnect the brake line from the caliper though. I kept the stock calipers

 

If you disconnected the brake lines then you need to bleed them.

 

As soon as you disconnect them it's only logical that some air would get into the lines. Bleed the brake lines and let us know if it fixes it!

 

I have no idea how to do that and the FSM is kinda vague

 

Check all your brake hoses and make sure you bleed just to be safe. Cap is on correctly on the cylinder. First thing i would do.

Cool thanks

 

Wow. Looks complicated! I will try it this weekend. Thanks!

 

So I need to buy a bleeding kit or something?

 

Looks like it. Or you can just ask a garage to bleed your brakes, less of a headache I imagine. Plus brake fluid will ruin your paint i it touches it.

^ Or you could try these ! I ordered them, but just dont have time to install, too busy of a schedule with the gym, work, kids, BJJ... If you search, some other members on here have had success with them. Check it out ! GL bro !

 

Did you bed in your brakes? I had my rotors and pads replaced per TSB and I had to do a few hard stops, from 60 down to 10, to bed them in pretty good before they started to have bite again.

I had to press my pedal 75% down before it started to bite. Now it bites at 25% depression and feels just like stock.

 

yeah I did do that just to make sure but it's still not where it should be. Considering the process of removing the calipers i'm pretty sure there's air in there. I guess I will find out this weekend.
