Hi everyone as promised.... My brake upgrade 

 

• Wilwood 4 pot Dynalite callipers with custom carriers (for standard sized rims)
•  
• EBC Yellow stuff pads
•  
• Racing green HEL brake lines

 

Braking force has dramatically increased, reading 322kgf registered per wheel, perfect balance and very strong bite and that aint even bedded in yet!

 

They look the business under the wheels 

 

what do ya think?

Look good - would you say they are better than the common 312mm upgrade?

Cost?

Do they use the same 288mm discs as standard?

These callipers are for standard discs and incredibly light

Can't comment on the 312mm brakes as I've never run them but

312 (1 piston) v wilwood (4 piston)

I went wilwood route as these were already bought before for my celica t sport, so Big thanks to vrs Joe for lending me his hub to get custom brackets fabricated up

Mine cost more than what is usually the price I think as I'm the first to do it...

So it was a development kit

I just wanted a brand new kit that was not only powerful but lightweight.., also Big plus is that these callipers can come with me to my next car, so long term investment really

The celica kit is about 425 if I remember correctly from freakyparts have a look at their website, I can't imagine the skoda kit would be far off, but I've asked for prices for both

Dynalite kit

superlight kit

Look good

Quite a lot of inner disk not being used though, do they do a slighter bigger caliper that would use the complete face of disk?

How have the brackets been made, billet alloy?

I'd definately be interested in these if they're around that price.

312 (1 piston) v wilwood (4 piston)

 

 

Don't mean to nitpick but the originals are 2 pistons, as there's 1 each side.

 

So your 4 pots have 2 each side.

I believe they are ally brackets very sturdy...

Even with the bigger callipers there will be some disc untouched by the pads, I was given the reason but for the love of me I can't remember!

I believe the pads are longer in length though, I will have to paint untouched area to prevent rust build up or if getting new discs go for zinc plated mtec discs

Lol not entirely true

312 - 1 piston each calliper

Wilwoods - 4 pistons each calliper

So far easy fitting no squeaky brakes hope it stays that way lol

lol! You been on the beer's! ?!?!

Standard only have one piston per caliper, the outer pad contacts the disk using sliders.

Willwoods have four pistons per caliper, two pressing on each pad

yes but when calculating the force applied to the disk it is 2 pistons opposed otherwise only 1 pad would move, action-reaction etc as the caliper is able to slide it is a piston.

Did loads of this when sorting wilwoods for the old felly and actually bought the little ones with 34mm pistons only to work out they had less area than the origional skoda slider with 54mm X2 piston.

It's not obvious at first tho 

So if the stock brakes are 2 piston (1 and the slider) what are R32 brakes? They have a piston each side? I'd describe them as 2 piston.....

exactly the same 2 pistons. it is really difficult to explain, the std calipers have 1 piston yea, but that piston pushes both pads together by using the piston bore as a piston area., just that the sliding side is less efficient due to the drag of the pins etc

Not really classed as a piston though surely?

 

Yeah the inner pistons force is what pulls the outer part of caliper via sliders to make both pads clamp the disk,but a piston is a piston!!!

 

What would you class a Subaru Impreza caliper as then that has two pistons in the caliper body both pressing onto the inner pad,outer pad is pulled in on sliders? 

Would this be a three piston caliper!!!!!

I counted 4 pistons on each wilwood calliper... Each piston pushed out as the pad wears so I count 4.... an example of 2 piston calliper is that what would be found on the back axle of a celica GT4 (as far as im aware) lol

 

In any case it looks and performs brilliantly.

I think you'll warp your disks next, With that pad/caliper combination and new fluid it'll take pretty much what you can throw at it. Just try to let it cool down properly before stopping.

 

 

As regards the caliper sizing and measuring applied force etc. When sizing components of an opposed piston caliper, you only count piston area(s) of one side of the caliper. As for measuring braking force, if it's done at the wheels or of the car as a whole, it doesn't matter what number of pistons are there, it's measuring the performance of the completed system.

Shame there is no dust seals on these, remove and clean every 6 months and even more in winter

I'll stick with my 312's - good enough for my standard vRS SE, the standard brakes are adequate at best.

This has been done to death a MILLION times.

There is nothing wrong with the standard brakes. They will trigger the ABS even dry roads.

312mm are better for fade resistance. And there was a theory that with bigger tyres you could exert more stopping force before the tyres lost grip and ABS kicked in.

Multi-piston setups are better because they spread the force more evenly across the brake pad/disc surface.

There is no evidence whatsoever that any brake upgrade is a bonus over standard as all they do is trigger the ABS earlier.

I have a variable bias Kenny McKinstry setup on my car with 312mm at the front and 288mm at the back and the car doesn't stop any quicker but it does look better. I have the variable bias because I was sick fed up of the rears grinding due to lack of use.

The dust seals (or lack of them) would concern me, but no doubt they look better and will perform better than the standard OE 288mm set up

The dynalites are meant for smaller lighter cars with smaller discs iirc. Still looks good though!

No problem with lending the hub Jay, pleased to help.

Which kit uses the 312mm discs? Dynalight or Superlight?

I can only go by celica standards mate, on the celica gen 7 the superlties go with 324mm discs.

Obviously they would perform better as their bigger but again more costly

I'm pleased with my choice nonetheless, even the superlites will not cover all of the disc... Bear that in mind

A combination of fresh brake fluid good pads and braided hoses contributes to much better braking, these forged dynalites are very light, half the weight if not less than the oem setup,

In Terms of no dust boots, I believe it dint have any as under heavy braking the rubber would swell n lose its integrity... it would need occasional brake cleaner + light scrub with toothbrush no biggie

We must get together on a track or private road and put this to the test standard v brake kit I'd love to see this just to satisfy my own curiosity, to me the brake kit makes a big difference as my braking just feels razor Sharp and on point...

It can make the difference in situation if your suddenly cut up by someone or a similar situation occurs, don't u think??

I'm sure it's not a placebo effect lol

Brakes that are too "bitey" are not good during fast driving in my opinion. They less hard you need to press them in order to lock the wheel the less control you will have if ever you need to brake while in a corner. As thry will be to eagar to grab and brake grip.

.comes under the category of light vs heavey steering to me. Lighter steering means you cant feel the road as much when cornering.

But I do need 312 brakes :( just need to get sone money saved

You don't need to save money! Your a secret millionaire all that money you've spent on yours sell me your turbo then you can have the new setup eventually and in the mean time you can have 312mm brakes
