Toyota Levin Issue

A friend of mine has a toyota Levin. He took off his calipers for spraying last week and when he put them back on the brakes were not working. He has bled the brakes and checked for leaks and air blocks. Everything was fine, so he thought the maste cylinder might be faulty so he got a second hand one and still no luck. Is there something he could be missing or something else causing this? He gets pressure on the pedal for a second then it goes straight to the floor... Anyone any ideas?

sounds like air leak in the lines or else its loosing fluid, park it over paper or cardboard and press break see if theres any leaks. did he bleed it in right order back right back left front left front right and keep topping up master cylinder while doing it

As pete said check for leaks pump the brakes and watch the fluid level in the tank if it goes down. when he is bleeding the brakes he getting fluid through the lines??

Loads of fluid coming through the lines and proper process was followed but no pressure on pedal??

not sure on toyotas but didnhe bleed the mastercylinder its self??

If using a bleed bottle with clear tube attached to the nipple check closly the fluid coming out if its with air bubbles air might be getting in the after replacing the master cylinder for a new one i cant see a problem

check the slave and master cylinders, use the bleed method that Dave is talking about and make sure the resavour stays topped up

got it sorted calipers were on wrong sides...

that wouldn't have helped

Thank god for that
