Other soloution would be rebore master cylinder to a bigger bore cylinder and use bigger seals !

dot 5.1 will not make pedal harder or soft is just have raise boiling point ! the master cylinder is small even for the standard brakes maybe you can try a cavalier 2.0 master cylinder if you lucky to find one as was told it will fit or a mondeo one with remote reservoir bottle

yeah it stops ok just the pedal is very soft and if pushed hard it will go to the floor

bleed it then or top up your fluid as a 4 pot uses more surely

there is no easy fix mondeo one has to be modded iirc ,bleed well and fit st/ steel brake lines, have a v6 set up works ok but the master does let the whole package down a bit still stops ok.

What do you mean not up to the job? Everyone else runs a standard master with-out problems.

There are only 2 different Corsa masters IIRC, one with 2 unions the other with 4? (It's casting my mind back about 5 years!?!) so upgrade within the range isn't possible.

I have heard you can fit a mondeo master but I do not know which one and I cannot confirm it.

Hello i have a let in my corsa so i upgraded the brakes to 4 pot wilwoods. The trouble is the master cylinder (still running 1.4 brake cylinder) isnt up to the job

what will i be able to use as a straight fit which will cope with the brakes

thankyou
