[studogs80]

I bought a Leganza and the brakes were all stuffed. i replaced all the brakes and rotors and for some reason it still stops poorly. The pedal is to the floor it stops sort of medium. my 2004 elantra and 2007 toyota camry stop perfectly and there brakes are 50% worn. Leganzas are brand new. I have been back to workshop a few times and they say its fine. i dont think it is please help im worried
thanks in advance:)
cheers

New brakes need some time to bed-in. But brake pedal hitting floor is a problem. Did you bled all air from master cylinder/lines/calipers/pistons brakes in the correct sequence?

dont know because a brake place did it. i'v taken it back many times but they say theres nothing wrong but i think there a pack of idiots!
i'll take it for a second opinion.
Thanks for the tip

can be a master cylinder issue or system needs bleeding
