RC Driving Style
hi, i have just bought a secondhand mugen mtx 3 and when i touch the brake slightly the back wheels just lock up. it dosn't matter how much i back off the adjustment the brakes are all or nothing, as if they are grabbing the disc. besides stripping them down and changing the pads, i wondered if i could spray somthing on just to render them usless for a while. the problem is i'm racing it on wednesday and won't have time to change them. hope someone can help
 
I wouldn't spray anything on them--you never know when you will need them. There should be two collars on either side of the lever that the brake linkage from the servo runs through. They are held on with a grub screw. You can move the two out toward the end of the linkage a bit, there-by easing off on the mechanical leverage applied to the brakes.

I am not familiar with your rig, but there may also be an adjustment screw on the brake plate itself. Experiment a bit and get back to us if this does not help.
 
If I remember correctly when I had my MTX-3, you should be able to adjust it with the linkages on the servo.

i have recently been told that it could be because i have a one-way diff on the front, and that i will only be getting rear wheel braking. a bit like pulling the hand-brake on in your car at high speed.
 
Ya, with one-way using the break is like pulling the hand brake. You can place a long fuel tube on the brake linkage which will give you a softer feel when you apply the brake.

WRONG!!! A spring will give you a softer feel and more play! A solid piece of fuel tubing will give you ZERO play and a solid feel.

EPIC FAIL!!!
 
I was going to say that shortening the fuel tubing on the linkage will help him to get brakes to engage at a later time than slightly touching it, but I thought GPM already said that. Guess I read it wrong.
 
Well, I never use spring in on-road cars. I use it in buggy as the traction is much lower with fuel tubing you will just lock up the wheels without any "linear" feel. For on road I use a long fuel tubing for the brake as with the faster speed and traction by the time I get some brakes I will past the turn already. LOL I usually run shorter tubing for front diff or solid axia and longer for one-way as it give you a slower more linear brake response. And it depend on the track design and condition as well. You can sure run a spring on an on road car and if you are running at very low traction condition. Sorry if I confuse you. :\
