brake calliper rebuild

[weeds]

just got back from a week on the beach and nursed the defer home the last 200 odd km as the brakes were a bit noisy.......towing a 1.1T trailer

just pulled the wheels off and the front and rear passenger discs are destroyed due to only the outer side of the calliper working i.e. plenty of meat on the inside brake pad but the outside pad are down to the metal

why would this happen to only the passenger side callipers? the drivers are wearing evenly

what goes wrong with a calliper for only one side to be working......i assume something wrong with the pistons

are they worth rebuilding?

is it easy enough to do?

are M R Automotive open tomorrow

Hi Kelvin, theye are easy to rebuild, wierd how they are only on the left....:confused:

There should be a tutorial in the good oil?

These guys split the caliper body, this is NOT how I do it as the Orings do not come in the piston and seal kits. (Edit: I just noticed he didn't show you how to fit the actual caliper piston main seals, but that is pretty self explanitory.)

If you have time up your sleeve, buy new calipers from the u.k., works out quite cheap:)

There dead easy to do but I would say you will be looking at two pistons and there rather expensive here. But a good seal kit from a brake shop should be cheap and have the channel seals in the kit either mcx or ibs kits are fine. Good luck getting the seized piston out tho. And once it's apart I sand blast the calipers before reassembly any questions just fire a pm I build up all sorts of calipers

While the caliper is still on the vehicle take the pad out of the seized piston side and pump it loose with firm pedal pressure. You'll probably find it's the outside pistons that are sticking as they haven't retracted therefore wearing the pads prematurely. If they haven't rusted a good clean of the piston and cavity will get it all working gain.

Unfortunately I have seen some absolute rubbish calipers from UK, one pair I got a while back the pads literally fell straight through:mad::mad:

Better getting a secondhand set of genuine ones here , Puma ones are the same.

For the price of the pistons alown I think would cover the price of a good late model caliper the last ones I got I think we're 40 bucks or so each to me(from memory) so 70 or 80 each to you plus kits so I would go down the second hand road and get a pair if ones knackerd the other generally wont be far behind and as Justinc said avoid aftermarket knock offs

Could it be that the trip to the beach and being parked together with the wind blowing sand into the wheels seizing the calipers?

[460cixy]

It will be rusted in there the boots on the calipers are junk it's realy just a dust seal and its not even very good at that.

picked up new rotors, seals and pads today..........

i will have a look at the callipers when i get them off.......

heading off the rocky tomorrow.....in the other car so it will have to wait till my return

Replacing the pistons & seals is a simple job, you just have to be clean and methodical. It's also worth investing in a couple of hose clamps to clamp the flexi brake lines.

FWIW - When pushing the new seals in, I use a little bit of new brake fluid to act as a lube. I then use a wooden ruler to press into place as I find it helps prevent 'nicking' the seal while maintaining an even pressure.
