My wife and I have recently bought a '94 sprite that has only done 16k from new and was standing round for a bit before we had it.
I've just had to replace the pads on the front due to the n/s going down to the metal. The o/s where probably about only half worn.
Also this wheel locks up a lot more easily than the o/s and it does pull to the left a bit.
So I'm pretty sure that the caliper is binding a little.
What's the best way of freeing it up? Is it to pull it off and take it to bits, or are there any other 'tricks' that I can try?
Thanks

Seized caliper?

If the car's been stood for a long time it's probably siezing due to corrosion of the bore or piston. The best thing would be to get it off and inspect it on such a low mileage car. Take the pitons out and inspect everything but don't split apart the two halves of the calliper, that's engineering shop only stuff.

If it is looking corroded, can it be cleaned up and lubed, or is it time for a new caliper?

Depends how deep inside the bore it is. If the piston only is affected then it can be replaced with stainless, if the bore is corroded only as deep as the outside of the seals and as a result the seals themselves are distorted which is holding the piston then it can be cleaned and reused. If there is any pitted corrosion down past the sides of the seals or into the bore where the piston travels then the calliper is scrap realistically. You should overhaul both callipers in order to get even braking, especially if you end up fitting new or stainless pistons.

Cool, thanks for the help. I know what I'll be doing over the weekend
