Hi I am very new to trials Aswell only got my first bike a few weeks ago I am from near forres

OK thanks will look there do they do just the o ring as a separate part

Mine is leaking when back together and on the bike it was OK went for a ride then next day brake was soft and I now notice a little bit of oil coming from the join between the 2 halves

Does anyone know if you can buy the small o rings from anywhere as brake is working just fluid seeping out of the split and I think air getting in there making brake soft

I still have the disk guard on I split caliper last week and o ring fell out now it's seeping is the a certain way to put oring as one side is flat one is rounded

Anyone know the size of the little o ring between the two halves of a 4 pot grimeca caliper mine is oozing brake fluid from between the two halves

OK will try that I had thought it could still be air just glad I am getting somewhere good luck with your trial I am really new to it just getting practice at the moment

think I have got somewhere now stripped caliper pistons out and drained master cylinder cleaned and rebuild little bits of dirt in the bore behind the piston bled system have a lever now and not sticking just lever is a bit soft is that just a case of adjusting the pull at the lever or something else thanks for all the help on this

I have tried the brake on the bike it works but just gets more and more pressure at the lever and pistons stick making brake bind I have adjusted lever all the way out still same thing happens

Do you all think this could be caused by air still being in the caliper as I xan easily push pistons back with screwdriver or by hand if caliper is split after this brake is soft pulls back to bars and after a few mins riding gets hard and outside pistons have stuck out really annoying Me now just want to get out and practice lol

I have tried all the things suggested in the post but still get this very hard lever after a couple minutes of riding and pistons out a few mm not sure if it's still air in system somewhere or something else

Hi everyone after a bit of help I have recently changed the front pads on my 2005 rev 3 I had to push the pistons back to get new pads in this was easy no corrosion and pushed back with my thumbs however I did split the caliper to make this easier.I have back bled the brake and don't think any air is still in there now my problem when I push the pistons back I have no pressure at the lever if I pump a few times I get pressure but after a bit of use the pistons stay out about 2-3mm and brake gets very hard not much movement in lever if I push pistons back some thing happens over again Any ideas what would solve this or advice would be great as I am confused over this at the moment thanks

I have managed to get a lever now brake works well so thanks for pointers but now when I pushed bike into shed the front brake is sticking a bit I can see pistons in outside haven't gone all the way in I pushed them back with my thumbs when changing pads so thought they were OK could thus still be air trapped

Thanks for reply so the problem is still just air in the system will have to find a big syringe and try that

Hi I was out on bike last week and front brake felt a bit soft lever was pulling about two thirds back I had very worm pads and changed them now the lever pulls back to the bars I have tried bleeding but no change don't know what else to try and help would be great

Mine is an 05 it is the rear pads I am having problems with there is no spring clip just an Allen bolt holding the pads when I try and put the inside pad in I can't get it down low enough as I hit the hub

Got the outside one in do you need to remove wheel to get inside one back in

Noone changed rear pads on a rev 3 does the eye go in towards the front or rear of the caliper

hi I have just bought new brake pads for a 2005 beta rev 3 and have managed to get the old pads out but cant seem to get to the new pads in has anyone any tips on the best way to put the new pads in I am obviously doing something wrong pistons are all the way back so the are not stopping pads going in I am trying to put the bit that sticks out into the caliper first then turn it towards the rear of the bike but cant get the back edge of the pad to go back into the caliper any advice would be great

I have been trying to hop the front end but when try the rear brake is not holding to allow me to get the front up riding along it will only skid if my weight is right forward any tips on what I can try to get rear breaking working better

Yeah thanks for that it's going now

I have just wired a jitsie kill switch to a beta rev 3 done away with original kill switch does it matter what way round it is wired as bike now won't start

hi all just in the last week bought my first bike at the age of 31 having been to watch my cousin ride trials when I was about 13 and always fancying it anyone else in the local area who could point me in direction of anywhere to ride I am just starting of learning basic control as of yet but cant wait to make progress and getting practicing

Hi very new to trials just learning bike control recently bought a 2004 rev 3 and on checking clutch fluid the rubber seal under the metal cap is knackered anyone known what this is called or where I can get one from thanks in advance
