Yes Al140, the important thing is not to damage the outersurface of the pistons. No nicks or scratches that would damage the seals.

This is the yool I use. Originally used to remove clips from drive axles.-Mike

 

Great advice guys. Bought these for job. Will keep you updated on progress when seals and tool arrives

 

Ideal, hope all goes well.
Cheers

That looks way better than the air compressor I used haha. Good luck and please update us later

 

Will do. As soon as everything arrives in post will be straight into hopefully getting it sorted.👍

 

Please make it a bit easier for yourself and also buy special brake caliper lubricant.
I had some minor pitting on my brake pistons and used a 2500 grit polishing lap to remove every nasty piece of crap and other stains.

 

Now there's someone that likes to live on the edge! Don't use a compressor and air to remove. That is really dangerous. Luckily if they're not frozen in place, they come out pretty easily.

Not slamming ya SunBlue, but just making people aware. Someone not totally aware of what they're doing could get hurt.

 

For sure man totally agree, the piston can go off like a literal bullet without the proper setup. The first time I used this method, I was stupid & unaware how hard it would pop off and did not have any set up in place. The piston went shooting by me, it could have smashed into my roommates car or into the wall or caused injury to myself, but, of all the places it could have flown, it flew into a tire in the garage and bounced off gently into a towel I happened to have heaped underneath. Lesson learned and after that I used a wooden jig that the piston could bounce off of. So I definitely support spreading awareness and I would 100% any day recommend a proper tool instead like what he got.

 

Well finally got round to doing the work. I have to say the removal of all but one of the four pistons on front was quite easy pumping them out to a distance using brake lever and then removing with tool i got. Ensure you have a container to catch brake fluid in when pistons come out. As always you get the awkward one which i had to get a friend to blow out using compressed air. When i removed the seals there was a fair amount of crud under them which took quite a while to remove with a pick tool being careful not to be to rough with it. After making sure there were no more deposits i cleaned the inside with brake caliper cleaner. When completely dry i used red rubber grease on new seals and inserted them into calipers. I then gave the pistons a real good cleaning and if needed a sanding with very fine sandpaper. Thankfully they did not need much in way of cleaning. The repair kit was excellent it had all the seals, banjo washers and bleed nipples. After reassembling the calipers it was only a matter of bleeding the system which again was uneventful. Because it all went well i decided to give the rear brake an overhaul as well. All went according to plan. I think i will make it an annual event to clean them well. Thanks for all the advice guys.
Should have mentioned I gave the slider pins good cleaning and replaced the rubber boots putting some red rubber grease into them.

 

Don't you love it when a plan comes together, I would think every other year would be enough when you replace the fluid as they should not get that dirty!
Where did you get the (very comprehensive) TRK kit from?
