Hi Debbie, just an update on how I fixed my 25 year old Zippy 90. I replaced the sponge brake www.andeeknits.co.uk - a proper Silver Reed spare part, NOT insulating foam tape - it does not work!!!! You have to remove all the needles first BEFORE you remove old strip. Make sure fabric on foam is facing upwards when fitting new strip. When replacing the needles, make sure you hook the needle in such a way that it compresses the foam .i.e. so you can see foam strip underneath the needle from reverse of machine, quite fiddly. Took me about 2 hours to complete the task. I then sprayed the needle bed with antistatic spray and, hey presto, it knits like a dream. Am knitting a pink chunky cardi for my new forthcoming grand daughter already! I love my Zippy! Good luck with yours. Jenny
