Options for 4 wheel disc? - Toyota Yaris Forums

Captain Slow · 12-31-2011, 06:48 PM

I dug up some threads referring to a Runstop kit for 4 wheel disc brakes, but MicroImage no longer seems to have them. Are there any other options for convert to 4 wheel disc?

thanks!

since the 2012 Yaris is now available in the US with rear discs on some models, and the rear suspension appears to be identical, it should be possible to do a swap... But if it's anything like with the OEM rear-disc-equipped 06-11 Yaris, that would require swapping the whole torsion beam too. Not sure why, but I guess the brakes mount differently...

or all we need is an adapter plate/hub spacer in one! That would be kickbutt.

The secret to efficient braking is...DONT USE YOUR BRAKES!

When I drive up to a red light I take my foot off the gas. The IDIOTS next to me pass me going 60 mph 200 yards before the light then SLAM on their brakes to come to a stop.

When you need your brakes is in the mountains. Drive down Pikes Peak sometime. You need to be in second gear because the ammount you would use yor brakes would burn them out. Burn out your brakes and its over the non guard railed curves you go thousands of feet to your death.

Driving in traffic to work (90% of our driving) is childs play compared to that.

hey im with you on that. i just want rear discs for esthetics lol. I already upgraded my fronts to the oem 275mm, i wanna finish it off!

agreed, it's mostly for aesthetics, I'm aware of how brakes work and know that rear discs are not necessary for commuting....however I'd still like rear disc brakes if possible ;)

find a junkyard Yaris with rear discs and strip it

One thing you can do is to ride a motorcycle with independently operated front and rear disk brakes. Try stopping as fast as you can with fronts then try it with the rears. The rears do about 10% of the braking.

The rears suck so bad most people riding motorcycles dont even use them. They can get you in a lot of trouble. Its far easier to lock the rear brakes than the front ones. And if you do that while on a curve you put the bike on the ground. Right now! In fact if the surface of the road changes its friction due to temperature, crap you cant see on the road, humidity or some such like that, the rear brakes can lock very unexpectedly. Possibly killing you.

The only thing is...

Those pads are a heck of a lot easier to change than the shoes of drum brakes.

Yeah, but you only have to do it every 300,000 miles or so.

it's funny though, persoanlly when on a bicycle or motorbike I prefer to use the rear brake, I once locked the front wheel and flipped over the handlebars, and it's given me a pathological fear of front brakes since then

precisely. I've built motorized bicycles and I never even install front brakes, rears only. i can handle some back-end wiggle, but I don't like going over handlebars.

bronsin · 01-01-2012, 02:47 PM

Yikes!

Well if you are still alive you must be doing something right.

Captain Slow · 01-01-2012, 08:17 PM

^ a valid point, shoes do last a very long time.

again, it's mostly an aesthetic thing, if it's not easily doable with a kit of some kind then I'm not that concerned with it.

I'm saddened to see that Micro Image no longer carries the rear disc conversion. It was nearing the top of my Must-Do list. I'd better get those lighting upgrades ordered before they disappear too.
