hi guys new to here need some advice, I changed my v40 s driveshaft yesterday fitted all back together and it drives fine but it does not stop when I changed the drive shaft I tied the brake caliper up so the hose was not under any strain now when I brake the pedal goes to the floor but theres hardly any braking force theres no brake fluid leaking, the lines dont seem to be bulging or expanding, so I am thinking must be the brake master cylinder is letting fluid pass the seals as the piston is moving what are you guys opinions on this? any advice appreciatted
