Peugeot 406 23.8mm Master Cylinder

2 port brake master cylinder from Peugeot 406 - direct fit to 205/309 GTi when fitting larger front brake calipers and plumbing for a front/rear split on the hydraulic system. 
 
We would recommend going to this size master cylinder when using anything bigger than the 266mm set up or any 4 piston calipers. If your unsure please feel fre to contact us to discuss your set up and we can advise what will work best.
