Obviously 4-pots or any other brakes with larger pistons in the caliper than standard will increase brake travel. Putting 2 relatively large pots on the back will increase travel further compared to the tiny drum cylinders. Add to this the crappy servo found on Escorts, and it's not surprising that you need to stamp them to get real brake bite. However, once you get used to it, you'll see that a Cossie style setup really is very good (especially with warmed up race pads) - I've had many laps of the ring, and never any sign of fading or poor performance. I'll never out brake a real race car, but compared to your average daily driver it's lots better.

Rear Cossie setup without bias valve doesnt lock up under normal to controlled heavy braking. However, 'taking the piss' braking will lock up the back wheels in the wet. And as we all know, taking the piss braking generally only occurs in situations where you really do want to stop in a hurry no matter how unstable the car becomes (unlike controlled heavy braking like on track) - so decide yourself if you feel it's OK to not spend the extra on the bias valve and laying new lines.

How could you ever change from an Eezibleed to the pedal and jamjar method?? Eezibleed works wonders on difficult systems, not to mention the speed and effeciency of using it - no mess and no wasted fluid. Worth every penny!
