couldnt figure out why i had no brakes. founr two threaded holes in the brake mount. its the plastic moun that holds the bearing for the center diff pinion. I had to remove the air cleaner, carb, alum gear plate and the brake assy. Geez! :eek: I put a couple button heads with thread locker. Am I missing and easier way to adjust these two screws in the future. i tried an allen wrench. thanks in advance
 
Re: brake adjuster grub screws missing

That's the only way I have done it as I have lost those screws last year on one of mine. Had to remove everything for 2 grub screw
 
Not really the best design. I don't think they had adjustment in mind when it was designed. LOL

When you loose the screws it's tear down time....

If only that diff gear would have been off to one side more it would be a lot easier with a long Allen wrench
 
long t-handle hex wrench

There is no need to remove anything but the left hand chassis side plate. Remove this, get a long t-handle hex wrench, slide it aganst the large gear- you may have to sorta flex the end of the wrench with your finger or a screwdriver to get it into the grub screws. same method to replace missing grub screws- except you will have to put the screws on the end of the wrench one its close to the plate that holds the missing screws. no, its not e-z the first time- practice makes perfect. shure as he$% beats stripping down the car to resolve the problem. give it a try- works for me 100%.

left hand chassis side plate? radio box?
 
here is a photo.- the sunlit area shows the end of the allen wrench going into the upper screw- the allen wrench must be slid on the backside of the gear to get to both screws- no need to remove the radio box- just the long plastic piece that keeps dirt-mud out of the left side of the chassis.- left hand chassis side guard.
 
yea, check out the tubing on the break link- I have sorta mumbly pointer finger- the finger that controlls the throttle-brake- this is soft silicone fuel tubing for nitro cars- Useing the end point adjustment on the transmitter- I adjust it so that on any given surface i run on- low traction-high traction, when i apply full brakes- it almost- almost locks up the brakes- Heck, i have blue collar hands fingers- built to grab things- I have to type with 1 finger- right hand- but i am left handed--- go figure that one huh? lol.

That's a great tip!
 
Always do my best- lol. Also, as the breaks wear down these grub screws have to be cranked in so far into the plastic- It helps to go to the hardware store- Home depot comes to mind-- Buy longer screws- there will be more screw threads to grab the plastic. -
 
Those tiny set screws are the reason I'm not a fan of the aluminum bearing carrier. With the plastic version you don't have to worry about thread lock to keep them in place.
