I'm due to change the brake fluid on my Punto. Reading the Haynes manual, it gives a strong warning about ABS models. If the fluid is drained from the hydraulic modulator, the unit will become unservicable. Sounds expensive.
Haynes recommend using a pressurised bleeding kit on ABS models. From the description, it sounds like you attach a pressurised fluid filled container to the master cylinder reservoir. When you unscrew the bleed nuts, the old fluid is pushed through and immediately replaced/topped up.
Most of the kits I've seen, from what I can work out at least, seem to create a vacuum at the bleed nut and therefore pull the fluid. Is this likely to drain the hydraulic modulator or to be less specific damage the system at all? Any recommendations on a good kit?
