LiamWood! Posted March 12, 2008 Report Share Posted March 12, 2008 Tonight i fitted my brand new V!Z yellow pads on the rear.The rim is smooth little bit of tar.The brake just doesnt hold? it has a little bit of bit but not much.Also when i squeese my lever hard and release it when you pull it back in again it seems to pull in further for the brake to lock?Ive checked the cylinders for movement and cheack for leaks but everything is in order.Anybody help?Liam Quote Link to comment Share on other sites More sharing options...

Greetings Posted March 12, 2008 Report Share Posted March 12, 2008 It's best to buy brake pads from companies which specialize in such components. Usually, you'll find that the big trials brands expand their product range with brake pads just for the sake of producing every single trials part you can buy for a bike. This means you're buying pads which haven't undergone much r&d. Koxx is an exception but look at Echo, Viz, Monty - they're all awful. Give Neco a try or just get some Rock Pads, Heatsink or Plazzies. Quote Link to comment Share on other sites More sharing options...
Shaun H Posted March 13, 2008 Report Share Posted March 13, 2008 My J!Z yellows were really good on a grind. Wear rate was a bit quick though.I'm pretty sure the pads aren't designed to be used with smooth rims even if they are coated in tar. Leave it for a while if you want, but I imagine the only way to get them working satisfactorily would be to grind you rim. Quote Link to comment Share on other sites More sharing options...
The Duck Posted March 13, 2008 Report Share Posted March 13, 2008 Just don't every expect to have a good brake with an smooth rim. It just doesn't happen.Unless your (is it Danny Kearns?) who has some magic zoo pad set-up. I tried zoo pads on a smooth rim, they weren't that good, hold was wank, and one little bit of water = no brake. Quote Link to comment Share on other sites More sharing options...

Alex Dark Posted March 13, 2008 Report Share Posted March 13, 2008 clean the rim with white spirit, and sand your pads down a wee bit in case either is/was contaminated Quote Link to comment Share on other sites More sharing options...

CC12345678910 Posted March 13, 2008 Report Share Posted March 13, 2008 (edited) Step 1. Clean the rim with muc-off degreaserStep 2. sand the pads down with 20ish grade sandpaper (really rough) Step 3. go down a step hill as fast a possible (I get a mate to push me on a MTB) with brake on until it squeaks like fook Step 4. lightly tar the rim. Step 5. Go trials!Oh and V!Z stuff ain't shit OK. Edited March 13, 2008 by CC12345678910 Quote Link to comment Share on other sites More sharing options...

eskimo Posted March 13, 2008 Report Share Posted March 13, 2008 Yeah... another vote for the suckness of them. I found Onza Citrus pads to be better. Try some Plazmatic CRMs. My brake was well good on a smooth rim with them, it also had the classic bite sound strangely enough. It does depend alot on the braking surface though!

Mark W Posted March 13, 2008 Report Share Posted March 13, 2008 Well i bought the pads becuase on tarty it did say smooth rim.I dont want to grind my rim, becuase my rim life will decrease!LiamLight grinds give you really good braking, and barely reduce the life of the rim at all. If you're doing really deep grinds every 2 weeks the rim won't last a hell of a long time, but light grinds are fine. My old Try-All rear rim lasted for literally forever because I only ever did 'medium' grinds at most, usually just light ones every 1-2 months. As soon as you use a brake on a ground rim, you'll never go back. Magura bled with water, Koxx greens and a fresh grind = moar. Quote Link to comment Share on other sites More sharing options...
The Duck Posted March 13, 2008 Report Share Posted March 13, 2008 clean the rim with white spirit, and sand your pads down a wee bit in case either is/was contaminatedDO NOT use white spirit. It leaves residue on your rim which will make the brake even more shite than it was before. Go to halfords and buy disk brake cleaner (for cars, black aerosol can) Quote Link to comment Share on other sites More sharing options...
LiamWood! Posted March 13, 2008 Author Report Share Posted March 13, 2008 Went out on bike tonight, most of the tar had rubbed off from the previous night but the hold is now mint!i was perposly going for the edges, pads are biteing and holding mint now!I have just replaced my citrus pads with these new V!Z pads and tonight there has been a significant increase of bite and hold!Liam Quote Link to comment Share on other sites More sharing options...
