Hi All
Anyone know of a cheaper option for wheel cylinders for my 1946 Morris 8 Series E. I've been quoted about £70 each!! Would mini ones fit?
Cheers

Rich,
Have you looked into getting them relined in stainless steel or brass? Maybe someone here could point you in the right direction.

Hi Rich
I have searched high and low for alternative replacement m8 wheel cylinders that could be easily adapted and unfortunately don't think there is one 
Firstly do yours really need replacing; they can and often are quite pitted right in the centre, but as this bit never has to seal its not so important. As Art has said , relining is a common option, if you know someone with a lathe it can be done at home, I did my own in stainless steel also made bleed screws and securing bolts in SS.
Cheers

| If you get them sleeved with stainless steel they will last forever. Need to find someone who knows how to do it. |

Thanks Gents. I could them refurbished but even that seems quite pricey. I was hoping someone would tell about an alternative part that would fit. Perhaps wheel cylinders from a mini or an 1100.

Hi Rich
You won't find another cylinder that will just fit. Any other cylinder will require modification to the back plate. Secondly the Pistons on most other slave cylinders tend to be slotted (where they fit the shoe) ;M8 ones are not. Finally if the replacement cylinder is not 7/8" both the brake pedal travel and required pressure will differ from the standard.
Non of the above mean that fitting a different cylinder safey is impossible, but it won't be a simple swap.
Cheers Dave |

Rich, don't look for inappropriate replacements or have yours sleeved in stainless.
Refurbish your existing ones. I did mine in a weekend armed only with a new seal kit, determination and elbow grease.
Oh, and some very, very fine wet and dry paper to polish the pistons. Doddle.

I have recovered a few this way too....A note of caution; this action may have been completed a number of times before!... each time slightly increasing the cylinder bore ... take care!

A good point, Dave. I was in something of a rush when I did mine in 2012, son's upcoming nuptials......
I imagine that the answer would be to accurately measure piston and bore diameters after "cleaning" to be sure that tolerances remain acceptable.
