simple Q for you lot lol

[novanutted]

i want to fit astra gsi turbo brakes to my nova when the 1.4 sri is in,do i have to change my servo?iv heard so many mixed opinions i need a definate answer as iam not willing to buy brakes not prepared to change servo!!

[Philsutton]

the later type brakes are different an you wont be able to fit them to a nova without major work. The ones you want are cav / calibra turbo ones

[Adam]

No you dont have to change servo.

What brakes are they?

[Mazz]

The easiest and cheapest way to get bigger brakes is swop them for 256mm Cav SRI/GSI, Astra GTE/GSI - its a straight swop..

SRI turbo stuff is 308mm, but IIRC the calipers are a different fitment to regualr Astra/Cav/Nova hubs.

Late Vectra GSi are the ones to use... 308mm. Different caliper carriers.

k reg astra gsi turbo brakes,all i need to know is about the servo

[Philsutton]

they didnt make a k reg astra turbo, however if it is a mk3 then the brakes will fit.

sorry yeh mk3,perfect advice thanx!!

the servo itself doesn't need swapping, but the astra/cav master cylinder is a bigger bore & it is a straight swap. it will stop better, but you may have to swap the hexagonal valves over.
