Dual disc brakes, worth it?

[crow2k80]

A friend of mine has a savage x like I do. We were both wondering about getting the dual disc brakes, but I saw somewhere here that it can rub on the clutch bell. You'd have to double mount the engine or something to that effect (which how would that be done, if needed?)
Plan b is to do the throttle mod I saw here, with the metal ring around the plastic, etc.

ummmm...I have no idea how your brake disks would EVER rub on your clutch bell...it would have to get thru your spur gear first...

 

[crow2k80]

thats what I was thinking but I heard a horror story about it.
It might of been an ss model.

I got dual breaks and they don't rub. Just make sure not to put any grease in the break hub, you need to run it dry otherwise it gets spun out all over your rotors and your breaking will be rubbish.

Thanks a lot for the info!!! I ordered the dual brakes and should have them in by thursday. does it come with grea when you order it?

imo the stock single fibre pad disk is much better than the dual disk setup. the dual disks are very inconsistant

I second that, mine always have to be adjusted. I ordered CNR brakes.

My experience is that the dual disks grip more, but they wear out more quickly too.

Another good thing to do with the HPI dual breaks is to add an extra set of pads to the centre metal caliper, also a small bit of fuel hose between the pads will act like a spring and ensure they don't bind. You'll also need longer screws.

I also found the HPI break pads were rubbish, the double sided tape they use comes apart if they heat up, use Hotbodies break pads, these don't come with any adhesive on the back, so you can rough up the metal calipers and use CA glue.

I don't even use the pads, I do metal to metal works allot better IMO.

dule disk stripped my 3 speed tranny case out and screwed by front difs up I GAVE THEM AWAY !!!

Same they stripped right out, I really don't recommend HPI DD Brakes.

Damn it I just ordered some for 16 bucks. Oh well I can sell them to my buddy if need be. So if I stick with stock, and use stock when replacing what tricks can be done to get full braking power. Right now I need about 20 yards to stop.

Take up some of the slack between the screws by using washers. Instead of using a spring or fuel line use a small plastic tube. You can buy them at Lowes.

Cool. I'll have my buddy try it out tomorrow since I won't get my brakes until friday. I appreciate all the help

I have had the SS brakes and the HPI DDB. I could never get the SS brakes to work at all. The DDB's work great and I run them a little loose. My thinking is that you never want to have full lock and skid anyway. I just want the truck to slow enough to stop and be safe but controllable. Stopping on a dime costs money imho.

 

[crow2k80]

i agree with you there davetens. I don't mind a slowing down to a stop, I just don't like the 30 yards it takes with the stock brakes.

For you guys who have lost trannys to the DD breaks, how exactly is that possible with a properly setup set of linkages? Only way that could have happened is if the engine was still engaged while you were breaking.

Not using the pads is a bad idea, seen alot of destroyed disks caused by that, the metal on metal contact really heats them up.

As for buying plastic tube instead of using a thin bit of fuel line, why? You'd normally have lots of bits of it around, why go buy extra stuff?

I checked mine didn't strip it just always loosens. The stock brakes have a wide thread, and the screw I use now has fine threads. It's kinda stripped and loosened.

that horror story couldnt have been on the new SS x cause i own one of those and the dual disk brakes are amazing....thier like brembos on you savage..stop on the dime

I don't even use the pads, I do metal to metal works allot better IMO.

how does that work....i tried doing that once but there are gaps because the pads are suppose to go there...did you use shorter screws ???

Sorry mate, miss read your post.

I don't used self tap screws in plastic since they tend to back out on their own, in anycase their the same screws that come with the with the single HPI fibre disk, they'll strip out the holes if your servo puts way too much pressure on the break setup, this again is down to how your servo and linkages are setup.

Longer M3 threaded screws are the way to go, not just on this but on everything that uses a 3mm screw.

Tighten the existing screws or use shorter ones, it wouldn't be difficult. Still a bad bad idea.

You know that little brass spacer in front of the clutch bell? I used 2 of those on the end to take up slack, you could stack washers or use shorter screws as well.

Who said anything about (lost trannys)?? do to the brake ?

read post #21.

i just put a piece of fuel line on in front of the brake spring where you adjust the breaks. it gives you a little more push on the breaks, but still spongy

Agreed, but better yet, use a piece of rubber fuel tube instead of silicone for more response.
