hi guys,

So I attempted to swap out my track pads for the oem and it was first time at the task. Anyways, I removed the caliper (front) and changed the pads but I noticed the piston was not flush but didn't need to be retaracted in order to clear the rotor. I wasn't sure if I was going to have to retract the piston so I removed the brake fliud resevoir cap in case of overflow and wrapped a towel around it. I reinstalled calipers but now my pedal sinks almost to the floor before brakes engage. Any advice on how to correct? Not sure what step was missed.

Thanks in advance

 

have you started the car yet?

 

did you pump the pedal several times when you where done to bring the pedal back up. If you didnt open the system thats all it could be.

 

I didn't actually pump the pedal before I started the car. I just drove around the block and then when a freind told me to pump the brakes, I did so after I returned. Still no joy. How do I remedy this?

 

I should add that after I pumped the brakes after I returned from around the block, the pressure did return after a few pumps but this didn't help the extremely low/late engagement. Basically feels like i have zero braking power until right at the bottom of the stroke.

 

your reservoir got low? do the new pads have less meat on them?

 

If the piston boot is damaged it can let air into the system. I would bleed my brakes if it were me first and give it a week or two to see if the problem returns.

 

only very slight wear over the track pads depth so I wouldn't imagine there would be that dramatic of a difference. The oem pads have at least 2/3 left.

 

didn't see any boot damage.

 

What type of pads did you put on? Did you swap rotors too?
