I am in the process of refurbing my sierra rear drums before fitting to uprights....lots of rust,dust and siezed bits so I decided to check out the price of a couple of brake slave cylinders.......for the price of a couple of pints I could have a new set delivered to my door....and yes you guessed it ....from ebay
£4.40 delivered for both cylinders, so no heating/cooling,WD40, mole grips, brake spanners,cussing.......just a couple of new bolts, it was a complete no brainer, some things are just not worth the hassle for the sake of saving a few quid here and there.
here is another cheapish set at just over £7
