Cheers to all who gave me advice on banging out old studs and replacing them with longer ones. Here's some pics to say thanks:

Standard wheel. No good for competition. But studs are too short to hold the Compomotives so I need to swap the studs.


Wheel off. Note standard disc and caliper:


Outside of the caliper off:


Disc off:


Tap studs out with a hammer (easier than I thought):


Short studs and new long studs:


New studs slip in:


Old pads:


Presing in the pistons in the caliper with a block of wood and a clamp:


Do the other half in the vice:


New disc on:


Yellowstuff pads:


Caliper back on:


Nice pic of new pads in place:


Bleed the brakes:


Job done. New wheel in place with new disc, new studs and new pads:


The car:



Typically I took about 90 minutes to do one front corner and 45 minutes to do the other side. Then I did the back. Jesus! That took some time until I figured out the easy way to put it back together.

A brake question. How important is the rear rubber dust cover thing that is around the rear caliper piston? Mine is shredded.

Cheers,

How come you split the caliper and didn't just remove the whole caliper out of the way (still keeping it connected) ??

Just interested.

I had to change the pads so the caliper had to come apart.

The caliper doesn't need to come apart !!!

Remove the 2 pins and slide out the old pads out, use a caliper piston spreader to push the pistons back all at once. Then no bleeding is required.

Ahh, OK. How do the pins come free? I thought they were fixed by the two halves of the caliper.

On the rear calipers, how important is the rubber seal round the caliper piston?

To knock out the pins on the front calipers just use a centre punch or something similar to tap them out, you can tell which way they have to come out as one end is bigger.

The rubber seals prevent dirt/grit/dust etc from getting to the outside of the piston where it slides. You can expect the piston to possibly seize in the future if the seal is badly damaged. It would be worth while replaceing them if you want your rear calipers to last a long time trouble free.

Race calipers don't have dust seals, because they strip and refurb them regular.

Never split calipers,how long will they seal for ? shouldnt play with brakes if you dont know what your doing

Odd way to do a pad/disc change!!
As said just use a suitable size drift to tap pins out, on eend as said is bigger and has a sprung clip on it to retain in, you are also MISSING the anti rattle clip on the pins, but not important if just track work.
Ace choice of pads, I use these on the road, best pad I have used.
