Title: are front brakes necessary? Post by: tikimadness on December 30, 2012, 17:28:35 pm Building my car I'm running discs in the rear and have a chute if the times come down.Is it mandatory to use front brakes?
Running spindle mounts now, I'v seen some options on how to mount a rotor to them but I'm inn doubt if that's the way to go if you are after single digits ;D Michael Title: Re: are front brakes necessary?

I haven't driven my car in its current setup but I intend to use the chute to stop it at the top end, however have now made the choice to put front brakes back into the equation.... With a spool I don't want tyres that have not been heated up as much as they could have been. I think I have also made the front of my car too light! Title: Re: are front brakes necessary? Post by: tikimadness on December 30, 2012, 20:24:46 pm I think I have also made the front of my car too light! Well making the front as light as possible was part of my plan so `i can add weight where i want it.But like always things run out of hand pretty soon so now I'm having a fast car without front brakes and that worries me a bit.Seen some guys weld discs to the spindle mounts and even weld things like studs to the wheel to attach a disc but don't think I want to hit the brake hard with that kind of set up Michael Title: Re: are front brakes necessary?

Because of the weight transfer there is enough weight on the front wheels for sufficient brakes. I have discs an front and rear and have run 9.176 @ 248 km/h so far, without a chute.

I thought they are too thin to weld those blocks to?

Ok thanks for sharing, still have a lot to learn... Michael Title: Re: are front brakes necessary? Post by: Jonny Grigg on December 30, 2012, 23:40:07 pm That is some nice craftsmanship MeXX, but to me it looks a little bit scary! You have had no distortion of the wheel or mounting with this arrangement?

Post by: Mike Lawless on December 31, 2012, 01:12:33 am I won't run a car without front brakes. But that's simply my choice. A lot of guys don't.
Here's a couple picks of my spindle mount set-up. American TrakStars on modified link pin spindles, with "funny car" front brakes. The brakes bolt right on to the the back of the wheel. Everything is pretty much off the shelf. I only had to make the caliper bracket.

It only looks scary. I've run this setup for two seasons with some hard breaking because of too short tracks and there was no distortion at all. But if you don't trust you can make the studs longer and weld them on the outer side too MeXX Title: Re: are front brakes necessary? Post by: henk on December 31, 2012, 14:17:31 pm @MeXX
what are the calipers that you are using from? look like radials from a motorbike? henk!!! Title: Re: are front brakes necessary? Post by: MeXX on December 31, 2012, 16:51:10 pm @MeXX what are the calipers that you are using from? look like radials from a motorbike? henk!!! Tocico is very light superior in quality and used ones are very cheap MeXX Title: Re: are front brakes necessary? Post by: funnycarmike on January 09, 2013, 21:25:22 pm Ther are currently al lot of "funnycar" spindle mount front brakes for sale because of NHRA mandatory carbon fiber brakes.

Post by: dragvw2180 on July 18, 2015, 15:52:37 pm After almost running off a short track like Mexx and also trying to evade an accident when someone crossed the line in front of me , I run front brakes . Are they needed, not until you get in one of those situations that you cannot foresee . Mike McCarthy

I have seen it done like Mexx, but the "studs" go through to the front, and are welded on both rim halves. That seems a bit more secure to me and would add minimal weight. I always envisioned it as being faced, and drilled tapped after welding to be a little straighter, but it seems to be working well for him. Those look like ZX10 rotors and GSXR calipers to me. |
