7Th Gen Celica Brake Issues

[mark1981]

Hi guys

I have an 02 7th Gen Celica vvtli 190 and recently I experienced a brake failure. The brake pedal just hits the floor now and there is absolutely no fluid in the reservoir.

I can not find any signs of a leak and i was thinking that the master cylinder seals had gone and the fluid leaked into the servo.

The part that i am confused with is because i understand that the clutch and brakes share the same reservoir so i was wondering how i pin down which of the systems the problem lies with.

I was hoping that someone could offer some advice on this issue or maybe if someone has had the same problems before.

Any help would be appreciated.

Regards

Mark
