I have seen thes brake refurb kits available and wondered how easy is it to change all the seals in my calipers. Only reason is i will be takin calipers off next week to clean up, paint, change discs, pads, brake lines and was wondering if it was worth while refurbing my calipers too if it wasnt too hard??

Advice please.

Easy peesy mate. Worth while if you are taking them off anyway. Just blow the pistons out, split them and renew the seals. Then put back together.

Any chance of a bit more detail of how to get the pistons out pal? And what do you mean by splitting them, Im guessin thats just a case of taking the 2 bolts out and seperating the casings?

Take a look at this dude. Did mine a couple of weeks ago. Really easy to do. Apart from taking them on and off the car it Took an hour and a half max to strip and put back together and thats going really slow.

Did'nt need to split the caliper.

Have fun

*although unless you've got a split dust seal / sticking piston, I really wouldnt bother*

Just to add that you should not split the calipers, they are sealed from the factory.

Its very easy to do , there is only a rubber 'O' ring that seals the 2 halfs , just make sure you dont lose it , and make sure its sitting properly before fitting the calipers back together.

Also, if you need new pistons get them from Mr Godney above and not the dealers - he is much cheaper

I did this last year and had 2 pistons that were seized solid and required lots of penetrating fluid and patience to remove. Just tapped them home then levered out a little bit at a time working them in and out until they finally freed off.

You definately DO NOT need to split the calipers.

The Subaru 4 pots use the same seal kit whatever year they are , I can supply you a seal kit for one caliper for £17.50 , and our stainless steel pistons for £15 each or £100 a set of 8.

If the pistons are sticking , it is easier to get them most of the way out while still on the car , take the pads out one at a time and pump the brake pedal , the pistons should come out , you need to put washers and a wheel nut on to hold the disc tight onto the hub , and you will need something about 5mm thick to put inbetween the piston and disc to stop the piston popping out all the way , do this to all the pistons then remove the caliper , and strip it down completely.

I have been taking pictures going through the process of rebuilding calipers stage by stage , and will be putting full details on my web site shortly , i'll put a link up once done

Cheers Ian
