No worries at all

it's common for the auto adjust ratchets to get stuck, and it keeps the shoes too far away from the drum. My pedal used to go almost half way until i fixed it with a good greasing.

Yes 180mm rings a bell. ABS ones are 200 ish - you'd know if you had them, they look ridiculously skinny.

I know the bit you mean on the servo, it's just a one way valve. so it holds a bit of vacuum if the engine cuts out. When the engine is running you have plenty vacuum when slowing down anyway.


Actually, if it's just lack of bite (sorry I just assumed it was maybe down to pedal travel), it could be something as simple as the brake pads being glazed. They might just need a good stamp from 50/60mph a few times. Or the calipers on the front might be slightly sticky.

I've just put new replacement calipers on mine with DS2500 pads and the bite is far better than before, the old caliper slides were sticky and almost stuck on one side.
