I know that numerous 2+2 and coupe owners
have upgraded their brakes and so here is a servo and master
cylinder upgrade which dramatically reduces the pedal travel
experienced with larger caliper mods.
Master cylinder source: 1991 escort 1.6 estate (25mm bore
size)
Servo Source : as above
Changes required
- One diagonal pair of pipes need the fittings swapped over
(big to small and small to big) to retain the correct split
diagonal arrangement.
- Change the servo end lever on the transfer bar to 70mm
centre length (from 55mm as was on mine)
- Lower the servo mounting brackets by 15mm (if you raised
the transfer bar to accommodate the extended lever)
- Space or otherwise distance the servo mounting bolts to
the servo bracket by 25mm to allow for the longer push rod
of the escort servo(i cut and welded back on 25mm longer).
The escort servo was 25mm larger diameter than the xr2 one i
had fitted.
Picture 1 shows
overview on master cylinder , the two fittings on the side
(not underneath) are the ones needing swapping over to keep
the split diagonal.
Picture 2, a general
view of the reservoir.
Picture 3 shows
the raising of the transfer bar in the original bracket to
accommodate the extended length of the lever arm.
Picture 4 shows
the added section to space the servo from the existing bracket(old
flange cut off and new one welded back on but longer), also
again showing the raising of the transfer bar bushing.
