Brake Problems

[DarkFire]

I am putting a new set of discs on and there is absolutely zero clearance room between the pads, the rod, and the discs. I feel like there should be some room for play so it isnt constantly rubbing. Any ideas?

there should only every be one brake disc in there, by the looks of the pic (hard to tell) your trying to fit two discs. haven't seen this done before.

My buddy has 2 discs on his. And according to the FG manual it should have 2

hrmm interesting, ive had 3 FG's from new and they have all had one brake disk, and ive only every run one brake disc.

if its tight I wouldnt run it as is, would cause more stress on layshaft would could damage bearings or gears and the added heat would definetly affect bearings.

not sure mate, if it was me id be removing one brake disc and checking the clearance.

I dremeled down the brake rod so it gave enough room. Now it moves smoothly. This FG is really old, I get my parts through DDM and this is what they have.

nah all good, i learnt something new, good work on finding a solution.

Check and make sure there wasn't two grub screws set in the plastic gear plate. This would cause it to have less room. Allows for adjustment later.

Yeah I made sure they werent sticking out. But after griding the rod down I have them popping out a little so they don't melt the plastic.

It's been a long time since I had that set up. Made me think a bit about the two disk set up..

Its honestly a pain in the ass. Need something new.

front discs are the way to go, i have them on my 4wd baja and are awesome.

Ideal set-up is a 4-disc one.

I have front hydros and the tuning layshaft disc - need it on my MT as it weighs 18kg / 40lbs !!
Stops without a problem.
Hydros are great when they're working properly, but are fairly high maintenance.
Tuning cable fronts with a good servo - Hitec 5955 / Savox 1256TG is a very good compromise.

FG layshaft tuning brake is a good set up.

Hydros are less maintenance than cables, cables are hard to keep balanced but with hydros there balanced and that's it.

I'm reaching the point where I probably need to pull apart and refit the O-rings so I'm on the point of not agreeing - I'm sure you'll understnad why Brad!!
Totally agree with the balance thing, but with (quite a lot of) care, I've sorted that on my 1/5.
Even when set-up, after a few hours, one side might 'bite' more than the other, thus wear more, thus will need adjustment ....

Im not bothering with any front brakes on my 2nd marder after running fg tuning cables on the other. A decent back brake ie the layshaft tuning brake, is more than capable of stopping it on any surface. As you say, cables can be set up perfect but you get outside and even the change in temp plays havoc with your perfect 'bench' settings. Then you tweak them again and 5 mins later its pulling to 1 side under braking so more adjustments required. They are a complete pain in the arse!

ive been running front tuning cable kit for a while and had to do no adjusting, they have been very reliable and been run on every condition you could think of including wet and wet sandy. thats my experience though.

id still go hydro's if I could afford them

Im either doing something wrong or its the UK weather with constant changes in temperature that plays havoc but they do my head in

i know if the fibre pads pick up moisture they can become very tempramental, maybe inspect the pads and see if they are causing the inconsistency.
