Front Brake Disc Replacement

[mark1gls]

The problem with a bigger servo is that it is easier to lock up the brakes and it takes longer to stop and you have no steering if your wheels are locked up under braking, in newer cars with ABS this is not a problem but is on older car without ABS.
A bigger servo does not give you better brakes it just takes less effort to use the brakes.
Can you lock up your wheels with the brakes you have fitted?
I think it's better to have a pedal that you have to press a little harder to stop as that is your natural reaction if you do have to do an emergency stop....

Have you driven another Scirocco or Mk1 golf as then maybe you can compare your setup?

Thanks for the reply, car presently has 9" servo (presume std fit). Was looking to replace master cylinder with 22mm version from MK2 Golf.
Have replaced discs, pads etc as mentioned in previous posts. Drove Mk1 golf and its brakes were better, my pedal is very soft (used easi bleed to bleed system) when I replaced the brake fluid. Going to bleed the old way at weekend to try and find improvement in pedal.
It is as though it is generating little pressure, that's why I am questioning the master cylinder to myself.

Feels like I am chasing the holy grail to find improvements.

Worth a go at re bleeding the brake fluid, I found it a pain to get rid of all the air when I replaced my master cyinder, front calipers, rear calipers, flexi brake line. It took a lot of bleeding with someone pressing the brake pedal and I found I had to start by loosening the connections at the master cyinder to the brake lines 1st then move to the wheel cylinders/calipers but I had dismantled and replaced the whole braking system when I restored my Mk1 Scirocco.

Use a clear pipe when bleeding the brakes to see if there is any air bubbles still in the brake fluid.

Your brakes should be somewhere near the Mk1 golf if you have the same VWII brake calipers.
