Wilwood 4pots squeeling!

[CageyJ0nnY]

Hello,

I have the ktec wilwood 4pot calliper setup on my clio running mintex1144 pads and the squeel especially when warm.

They don't do it when cool / cold and I'm wondering why this is as it's very loud :-S

Has anyone else had this? Or can recommend better pads if needed.

Cheers

Jonny

Pretty normal for those pads.

I had them in my Wilwoods and they done the same :dapprove:

 

[Ph1 Tom]

They have a smaller pad area than the standard pads so I'd run DS3000 or Yellowstuff

 

[Fletcher]

I have Compbrake 4 pots (they use exactly the same pads as the midlites) and run DS2500/ DS3000 without any Squelling.

Mines are exactly the same, gets really annoying at times!

 

[JamesBryan]

Are the pads free to move a bit inside the caliper?

 

[CageyJ0nnY]

Cheers guys. Might be a silly question but would copper grease help?

Either that or some ds2500s

 

[Paprika123]

It's the pad compound that squeals so no copper grease wouldn't do anything.

 

[Cup_Phil]

Don't put copper grease on race pads - the heat causes the grease to melt and run onto the discs

I run DS2500's in my wilwoods and they make no noise at all

 

[CageyJ0nnY]

Cheers Phil, I'll pick up a set.

Can't believe ktec sell 1144s for £100 :-0

 

[Cup_Phil]

Wow

I think the DS2500's are FRP502H which are about £60-70 a set when you shop around

That's one of the things I loved the most about the wilwoods - the DS2500's are cheaper than they are for standard calipers lol

These seem like the correct ones?

 

[George@RTR_Parts]

They do two very similar pad shapes mate, there's that one with three holes and the other is same size but has a cut out section where the middle hole is

 

[CageyJ0nnY]

Oh s**t, just bought that one in the link above! Will it fit?

 

[Dan@SJM]

It'll fit, you just have to cut out the centre to allow the pad locating pin to slide in

 

[CageyJ0nnY]

Ahh Ok, is it worth me ringing them and changing to the one that's cut out?

 

[Dan@SJM]

How confident are you with a grinder?

 

[George@RTR_Parts]

As Dan says it can be "modified" to fit so no worries. I could have got you those for future reference

 

[Dan@SJM]

What's your price George? I run them on mine (except in 3000's)

 

[George@RTR_Parts]

^ ill price match on any genuine like for like quotes Dan for the Ferodo Racing pads mate for people on here

PM me and ill get an up to date price for you as they've just gone up slightly from 1st January

Don't put copper grease on race pads - the heat causes the grease to melt and run onto the discs

I run DS2500's in my wilwoods and they make no noise at all

I think I'll try these next if you say the are silent. Can't stand squeaking!

 

[CageyJ0nnY]

I've canceled my order, they guy I spoke to on the phone recommended hawk pads said they were excellent / better than 2500's

I used to run Hawk pads with my 4 pots, they were awful when cold. IMO the DS2500 are much better.

 

[CageyJ0nnY]

Hmm is such a pain buying pads! You don't know if there good until you've splashed the cash haha.

The fella on the phone said 2500's needed warming up :-S

 

[Michaelfoz]

they might be horrible when cold, but bite like mad when hot

pretty common with track pads

corbon lorrainnes etc etc

 

[CageyJ0nnY]

Yeah ill see how I get in with the hawks and I'll report back

 

[Cup_Phil]

DS2500's don't need warming up at all

DS3000's are a track pad and aren't very good from cold. The DS2500's I have work just like normal road pads when cold (first mile or so) and then when you get some heat in they bite like mad.

 

[CageyJ0nnY]

I'm also not convinced there bled properly, do you need to do the top and bottom nipples? I've heard just the to ones need doing?

I am aware of this, but the hawk ones were terrible, fine once warm mind.

I currently run DS3000 pads in with my 4 pots and they have good stopping power from cold.

 

[Cup_Phil]

Just the tops as air rises in fluid.

on another note about brakes
what is the point in the wilwoods?
you have a bigger caliper pushing a pad with smaller contact area so therefore more pressure applied
however if it is the same size disc will they actually stop you any quicker?

the way ive been thinking about it is that if you have enough force avaiable to lock up the wheels with standard calipers, which you obviously do
then surely putting 4 pots on will only make locking up easier?

 

[Paprika123]

Lighter - less unsprung weight.

This. Also I got a good deal on them, and they look boss haha

Oh jesus. Are you trolling?
This has been addressed 800x

Cliosport is the only car forum in the world where people argue till their last breath that 4pots are pointless lol

It actually makes it easier to not lock up as they are more progressive than single pots
Less unsprung weight = better turn in
Cheaper pads
Much better heat dissipation

But honestly 30 people will be along in a minute to agree with you and say not even race cars need anything other than standard calipers #becauseburpspeed

 

[Michaelfoz]

I've never had someone say anything productive other than "they stop you quicker"

That's why I asked, suppose it makes sense that they are more progressive.

Never really thought about the weight savings

 

[Cup_Phil]

That seems to be what everyone concentrates on with bigger breaks - stops quicker

Like you say - adding braking force won't change the point where the tyres lose grip and the wheels lock up - to do that you need to look at brake bias and weight shifting during braking etc...

I'd never go back though. My wilwoods with bells + rotors cost me £700 but every track day I've done since they never overheat, the fluid doesn't boil anymore and you can jump on them soooo late.

 

[CageyJ0nnY]

Fitted the hawk fast road pads today. Just need to bed them in properly and see how they are.

Thanks for the help fellas
