Hard brake pedal

[acol]

Just had my 172 cup on track for the first time, the brake pedal seems quite hard and you really need to push the pedal, it's got wilwood 4 pots n braided lines is this normal

Checked the vac line is okay? They're known for melting and this occurs shortky before you get bugger all brakes and a solid pedal.

Ok thanks mick thanks, where does the line run from servo?

Back of the inlet manifold to the brake servo... its a thick plastic looking pipe from the right side of the coil pack that dissapears off behind the bulkhead lining.
