Caliper Seal Kits

GDay All,

Is anyone aware of where I might get some front and rear caliper seal kits for an FTO GPX 1995 model.

Im purchasing a set of calipers locally today (Adelaide) and given that Im anal about most things (in doing it right), I thought I cant go wrong in doing the seals. I will also be painting the calipers, and the above is to be a project which I wish to highlight here step-by-step with photos.

I would prefer to get them either locally or interstate, but my research in purchasing has taken me to the UK. I would purchase from OS, but only as a last resort.

Any advice would be greatly appreciated

cheers
Tom

Hi Tom,

I'll look up the part number on CAPS (Mitsubishi spare parts program) for you tonight. As you mention its a kit & you'd be able to get it from your local Mitsubishi parts dealer. The GPX calipers are the same as used on the Evo 2 & 3, and the main seals are common to a Mitsubish Triton I belive - so you wont get charged Mitsubishi 'import' parts prices.

Cheers,
Ben

My friend told me after restore the seal, the brake will back to original performance, is that right? as my car currently not running very good on brakes.

If you don't mind, can you look up the kit for GR as well please !

Thanks very much for your help !

I reckon my rear left caliper started to seize up,
making noise constantly, though there is plenty of meat left.

Not sure if my diagnistic is correct though, as rear left and right side pads seem to identical in size, I would have thought is a caliper is seized, that side should be a lot more reduced. Confirm please.

Does reconditioning caliper only involves changing the seals?

Thanks

If its seized Max then the seized pads would be meatier as they're not being used.

You probably have sticky sliders, which sound much less sexy than it actually is and doesn't even involve bleeding any fluids.

Get inside the car and remove the centre console so you can loosen of the handbrake as you will need to remove the cable to get the calipers off.

Pull of the rear wheels and undo the caliper as if you are going to change the pads, this bolt first.

in fact thats the only bolt you need to take off.

The boot goes through a slider pin which is sealed with a rubber boot. You can take the pin out of the boot and can actually remove the boot as well to give it a good clean and regrease it.

Once youve done that slip the top slider off, you dont need to undo any bolts, just slide it off and give it a good clean and a regrease

Once its all cleaned put it back together and you should have more effective brakes and a better handbrake to boot.

It only takes about 15 minutes a side.

I am assuming same part number for both front and rear calipers?

This may be a stupid question, but when buying a seal kit, does one seal kit service one GPX front caliper (which implies servicing 2 pistons) or does a seal kit pertain to each piston ??

Many thanks for the part numbers - now I just have to find a place that has them in Aus. without giving up your first born to purchase them !!

cheers
