sticking front brake!!!

I had this recently, both front calipers were seizing and one slider had rusted. I replaced the calipers with reconditioned ones they were about £100 each from autolink, and the slider was about £10. It only took me a couple of hours to fit it all.
I had a stuck N/S/F caliper. I replaced it with a recon, and replaced the O/S/F at the same time for balance.I bought mine locally from here, on a recommendation from another MX-5 owner:

The prices say £153, but that includes the £75 deposit (you get it back when you send them your old caliper). They also do the refurb parts, but I found it less hassle to get the whole unit swapped out.
I paid slightly less than that, so it's worth phoning and checking.
I had a sticking front caliper last week, so I took the caliper off (didn't take off the brake line) and had a look.
The piston was a bit cruddy, so I pumped the brakes a few times so it was mostly out of the cylinder then gave it a good clean, then pushed it back in with a C clamp.
I also gave the little lips at the tops and bottoms of the brakes pads a bit of a file, so that they were more free to move back and forth. Seems fine now

The calipers are not hard to refurb yourself at home.
Its corrosion on the pistons that causes them to really stick, not the slider pins. They get grubby, admittedly, and can cause rubbing, but the full 'brake locked on, wheel almost metling' syndrome that all MX5-s throw at you every once in a while, thats corroded pistons.

My mate said it was sum sort of white sludge it seems to b fine at the mo but if it happens again ill get him to change the pipes on it.
Sounds like the brake fluid is contaminated, possibly with water. Change the fluid if you haven't already.Worth investigating if there is any more build-up of this white sludge in the system anywhere. It could potentially act like a blood clot and stop fluid flowing to the callipers.
However, I'm not an experienced mechanic so I recommend you seek professional expertise.

I have hust fitted a HEL kit to a Mk2.5 turbo track car for a customer, would normally use Goodridge hoses, but no ready made kit available, the HEL Kit appears fine. Certainly fitting Goodridge hoses removes the problems with rubber hoses delaminating internally.
NOTE: The quick way to diagnose a delaminated hose is to prod the brake pedal with that corner's wheel removed, and while the wheel is sticking, open the bleed nipple, the brake will release as the trapped fluid escapes.
ALSO: Too many people replace calipers with re-con units only to find that the slider pins on the carrier were the problem, let someone look at it who you can absolutely trust not to fit unnecessary parts and then charge you for it!!
