English Axle? - Rear drums.
Firstly, am i right in saying this is an 'english' axle? - As fitted to my 1991 westfield?
Secondly, the pistons for the rear breaks seam to be totally knackered, one side atlease. Rubber boot was damaged, and further probing released a
large amount of rust and grunge and brake fluid, the lower piston is basicaly not moving, and the other apprears to be letting in air and it wont
bleed properly and also now leaking fluid.
Speaking to somone else apprently there drums [s]are[/s] use alumium single acting units, rather than mine which are steel bodied double acting.
Dont know if this is ringing any bells, but im thinking i might just replace the piston and body on both sides with new.
But confirmation of what i should be asking for and a ball part price would be nice, pads are ok.

you need to know the diameter of the brake drum, but standard mk2 wheel cylinders are between £5 and £10 each.

I think perhaps you are condusing drums a wheel cylinders, MK1 Escort (and other ealrly engilish axles) axles had alloy wheel cylinders with a single
piston.
MK2 Escort axles used cast steel double piston wheel cylinders..
Your axle would appear to be a MK2 Escort english axle --- it will most likely have 8" drum brakes. Although 9" drum brakes were fitted
to the RS models.
Fit a full set of brake shoes and a pair of new wheel cylinders.

Yes, sorry, slip of th keys in th origanal post. I am ofcause talking about the materal of the wheel cylinders (on drum brakes) rather than that
actuall drum itself. Orignal post corrected.
Sounds like i have a MK2 Escort jobbie then. Presumably therefore i want to replace them like for like with the steel units.

Just got around to geting with this in a lul between exams.
Ive got a pair of what ive been sold as new cylinders, from a mk to escort (non rs or giha). for £8 each.
However, although the casting is clear the same, and its double acting, the ends of the pistons are flat pads rather than the forked ends as on the
origanals?
- I can take them back if they wrong, but does that ring any bells with people?
Part s are Comieco 'brake engineering' part no. wc4920?

Looks like an english to me too. Mine has 9" drums fitted and also uses double piston steel cylinders.
Some of the cylinders are held in with a spring clip and others (like mine) with bolts. If you have the spring clip type, make sure you keep the clips
as apparetly they are like rockiing horse pooh to get hold of!

These are they. New and old.
The main castings arent exactly identical either it seams, and there about one 1.5 diffrence in piston diameter. Looks like this is going to be a more
involved jobe than first thought!
Clearly the new ones would fit, but wouldnt retain the brake shoes in the same way?
If its ok, i'll fit it, if not, what do i ask for when i take then back? (shut at 5,30)

Just been back to the shop and swaped it for somthing that nore looks very much more the part.
- The only diffrence now is there 17.4 bore rather than 18.7 (as mine where) but if im doing the pair that doesnt seam too bad (13% reduction)
espcailly as as it stands now the rears have been a little kean. Although that may be down too them geting a bit warm
