callipers 6 Years, 1 Month ago Karma: 80
right lads well i failed the nct yesterday because the passenger side handbrake cable wasnt pulling so i have the car up on axel stands and i have the calliper dismantled i think the piston is seized but not sure is the piston threaded? do i have to twist it back in or is it supposed to just be able to push in? ill take of the plastics next and have a look at the hanbrake cable propraly it seems fine so far

Yeah you need to wind it back in on the rears, it aint easy without a wind back tool but may be doable with a pliers and some cursing! Be careful not to damage things this way though.

right so i took the calliper off the car altogether because it just wouldnt budge, i have it in the vice and i made up a tool for twisting it but she aint moving much just a bit so i think the piston is seized so i need to get it reconditioned anybody know of any places in cork? or how much a new calliper would be?

Not sure if you have an air gun but if you do you can use it to force the piston out.
Just be careful because if the pressure is too high the piston will shoot out.

My mistake,though you were having trouble removing the piston. You need the wind back tool to replace the piston. Wind the piston in all the way then wind it back 180 degrees to set the handbrake mechanism. You might need to wind a little more to line up the groove in the piston with the pin in the brake pad.

Cozzy shop around. Mr2Ben is the most expensive (by quite some way) of any of the breakers I've come across.

Try Peter at S bits, I found him to be very reasonable when I got a few bits from him in the past, great customer service as well.
GTS Chris is worth a shout as well.

Try bathing it in brake fluid for a day and it should work free, then you need to give it a good clean down, refurb and reinstall. That's assuming you don't go down the replacement route.

Just buy one of these for your car. Then you can mess around with the one you take off as much as you like:

I bought 2 calipers off these guys they were perfect.

Or left hand one

www.ebay.ie/itm/Rear-Left-Brake-Caliper-...;hash=item35c6a91fca

Free postage also not bad. The calipers are a real problem area for MR2's best to hang onto the one you remove for the sake of 10£

Re: callipers 6 Years, 1 Month ago Karma: 80
me and my old man decided to have another go at the calliper and after a while we managesd to get the piston out so we sanded it down with really light sand paper did the same with the sliderss they were in an awful state bone dry so after cleaning them down and greasing them up we got the calliper sorted took it for a spin and found that the side we fixed was perfect but the driver side wasnt locking up so back into the workshop we took out the calliper on the driver side did the same again and its locking up now delighted the only thing is the rubber bushing in the slider on the top of the calliper is badly worn and the calliper moves a bit so i think this is the cause of the weird humming noise ive been hearing so ill let you know when i get this new bushing ill get through the nct anyway with the way it is thanks for the help lads

I did the seals on my rear calipers recently, fairly easy. I got a kit off eBay.

Re: callipers 6 Years, 1 Month ago Karma: 80
thanks bud kc, i already got that far with the two of them but i had no new seals so just cleaned them down and greased them up just to get me through the nct i will go at them when im painting the callipers in the near future. once the calliper is out of the car its really easy to work on, its just a pain bleeding the brakes after i did that twice today
