Brake master cylinder. Rebuild oem or pattern?

[gtmdriver]

My 1974 CB350F could do with some work on the front brakes.

Pacre Classic are selling pattern replacement master cylinders for £56 or so.

Does anyone have any experience with this component or the company in general?

Are these parts any good or should I rebuild my 42 year old component?

I would personally buy a seal kit for the existing master cylinder,they range from about £14 for pattern parts to about £20.00 for original.
Easy enough to replace with a bit of patience

Personally I wouldn't replace unless it is actually broken.
No experience with Pacre but I did rebuild my 400/4 MC using an aftermarket kit from DS.
Their aftermarket kit is £23.00 + everything, a genuine kit from them is £29.95 plus everything.
Has Coppertop got a cheap source of supply?
DS also do a complete aftermarket MC for £29.00 + everything - work that one out!
Replacement is not difficult as long as you have a pair of long circlip pliers to remove the internal circlip.

I also noticed (after having bought the DS parts) that Cruzinimage do a rebuild kit at £16.40 inc delivery.
Their carb kits are OK, don't know if the brake kit would be any good. It is certainly a cheaper option.

  I bought a replica master cylinder from DS,

 had it about 3 yrs,looks good,works perfectly,

you choose if you want the work of swaping the internals

I would go with John W with this as it is the cheapest way and the OEM one may be past the point of no return once taken apart.

Spoken to Peter at Pacre a few times ...seems a decent guy.

My CB750 has the DS replica master cylinder fitted, my CB500 the original. Nothing to choose between them in terms of feel etc. in my opinion.
