I totally disagree...
If you've de-glazed them by removing the working surface you need to bed them back in to get them back to a working condition. Bedding brake pads is not a 5 minute job. It involves using the brakes in a progressive way..
I keep reading stuff on here about how crap the stock brakes are but reckon most owners abuse them through ignorance! How many people bed the pads in properly? How many keep the full area of the disc in service?.. and -
Who fits an upgrade such as EBC ventilated disc set up and Green spot pads and then goes for a blast to see what the new brakes will do?? ... WRONG!... essential reading here -
http://ebcbrakes.com/articles/how-to-bed-in-your-new-brakes-for-streeturban-driving-2/When I raced a mini we used to pay for a track day at the start of the season mainly to bed the pads in as it's quite involved and can't be done during a practice session for a race. I lived in north London, not far from the Ferodo factory, and learnt a lot from the Racing Division guys about friction materials and how to set them up. In those days the pads were asbestos, sintered material and a lot of copper particles and the bedding process was slightly different to today. Here is the current procedure -
http://ferodoracing.com/products/car-racing/pad-bedding/If you've gone for a 'fast road' or 'track day' brake upgrade it may be more appropriate to follow the Ferodo procedure... but either way, you don't just fit pads and expect them to work!
Also, if you haven't used your car for a couple of months you'll need to clean the rust off the discs with something other than the brake pads, otherwise surface rust from the disc will get impregnated in the pad and rust-dust to rust-dust doesn't have a high co-efficient of friction. Once in the pads it's a devil to get them working properly again. It will involved taking the surface off the pads and then you've got to re-bed them. (I'm talking to UK owners here - doesn't apply to owners in hot dry climates where discs don't rust as you look at them!)
I try to use my Elan
at least twice a week, all year round, whenever possible. Unfortunately I've been playing around with instruments in it for a couple of weeks and my discs are now sitting there with an orange film of surface rust on them as it's sitting outside. Before I use it I'll be whipping the wheels off and cleaning the discs with a fine sanding disc in an angle grinder and then kitchen towel with meths to get all the dust off. Bit of a pain but my 'stock brakes' on this one still work just as well as the EBC set up on another I've got SORN'ed in the garage. They don't look as 'sexy' though!
