This new luk clutch master cylinder didn't even last a whole month... 28 days to be exact.

Why can't someone make a better version... guess I'm gonna have to i refuse to buy another luke... [rant][rant]

u squirtin' a banshee eh? i know a thing or 2 about that. used a vr 32-1 wheel on the flywheel though for ign control with an hei 2 pole coil off a gm 3.1l v6. worked awesome. just had problems with MAF software on the old ms2v3 (v2.831 code). i would like to try a micro someday soon on my cheetah cylinders. Would be sick to have all that power and running clean...more trail friendly.

let me know if your following me... Cause your thread topic is foreign to me. Why not use a stock master?

I seemed to follow that to some extent, up until cheetah cylinders [rofl]

The Luk is likely just a stock replacement but he probably doesnt realize there is something else causing it to fail prematurely... cause and effect, yes?

I put a LUK kit into my SVT after it blew up at FF '11 and I haven't had any issues. Have you had your car inspected for anything?

have you inspected your foot for laying on the clutch?

my gc had luk clutch and fly wheel from factory.... they are the cheapest shi++iest clutches ive seen... it started making weird sounds like 4 weeks after buying the car.

this is how it was when i finally took it off, dual mass FW and clutch was terrible too

Apparently you have a bad luck or don't now how to drive stick shift :) just my idea

Ya I get the Jist of wat ur saying... still in the gathering up parts stage till recently work getting slow with winter.... an I've replaced the clutch master cyc. 4 times now is a POS if they don't leak the linkage snaps

Cause > stage three clutch masters kit
effect > higher hydraulic pressure

So in that... I can see why it would leak, not ment to handle HP... but why they snap is just shty craftsmanship

Inspected... by me, I don't trust the stealership

An no I don't ride the clutch... but don't see how that would snap the linkage anyhow

Im 24 and owned 4 sticks... is at least one thing I can do right

I put a LUK kit into my SVT after it blew up at FF '11 and I haven't had any issues

I was there I think I remember if it happend on the strip

are you sure youre getting the correct SVT slave from LUK? because the SVT/getrag and MTX75 use different slaves even though they are identical externally!

Ive bought them from ford and auto zone an even ordered one from cfm once... all the same

I ordered a Wagner brand from Rockauto and got a Luk brand (OEM) with the serial number scratched off lol

So far luk is the only manufacturer of the MC ive found... no one even sells or makes anything different... im going to call wilwood to see if they have one that i could custom fit

Just curious, have you checked the pin connected to the clutch pedal assembly that actuates the clutch master cylinder. The pin can develop play. Ford uses a puddy to hold the actuating pin in place and it can flex. I went threw two clutch master cylinders and was like wtf? Finally my pin broke, had it welded on and have not had any clutch cylinder problems.

Only other things I can think of is maybe air in the system or improper install. I've never heard of people running upgraded clutches blowing out clutch master cylinders.

No, he was the one that was on the exit ramp before the hotels after FF11 was over.

is the luk the same as the one from the dealer?

Taking it down the strip definitely didn't help...the root cause was the flywheel separating from the crank shaft due to shoddy work from before I bought the car

Are you saying is the LUK the same as the stock clutch? If that's what you're asking, no it is not.

Ford made the clutch and flywheel available for order, but only for a limited amount of time. The OEM replacement hasn't been available for at least three years.

this thread is about the clutch master cylinder.... not the clutch

im asking if the LUK CMC is the same as the OEM Ford CMC

Rock auto sells 4-5 different brands of cmc's for dohc. Not sure if they are all for zetecs or not.

how much HP do you have

That I have it broke on my last replacement an had to weld it back in

OEM FORD, is it the same as the LUK that failed?

how much HP do you have

im thinking its his clutch thats the issue, not his HP numbers. the CMC wasnt designed for that clutch, is putting more strain on it.


thats my guess

thats my guess

yeah no kidding im not an idiot but if he doesnt make 300 or more he doesnt need that clutch and could downsize to a stg 1 or 2 both of witch have a good amount of grabbing power and less pedal force witch will put less stress on the MC.

Luk is the only one I've found... I get all the air out, I use a syringe to pull the fluid out until I have no more bubbles, been doing it that way for a while it's been pretty effective even on brakes.

^not really shur 185 is the average on my torque android app (if u don't no wat it is its acutely pretty cool) but I've never had it ran on a really dyno, I think my upgrades are in my profile

whats wrong with the motorcraft one from the dealer...... i dont believe its LUK. i just put one on this past fall. yeah i have a stock clutch, but ive been using it for 3+ months. call up tousley and see if the LUK and Motorcraft are one in the same, if not try one of those

Thanks u bet me to the punch...haha

Boost was in its nere future till I lost my job

no problem dude, thats what these forums are for. give him a call tomorrow, and see what he can do for you!

when mine went bad, it just leaked, it never snapped. you should also make sure there is no side so side play with the clutch pedal itself. any play will put extra tension on the plastic rod. thats no good! LUK could just be junk.

Always go OEM Ford from dealer, unless part is discontinued. Especially with the SVT, half the parts store order or sell you normal zetec stuff, the other half dont even know what a SVTF is!

lemme know what Steve says.

^^ ya no wat u mean... thanks an I will

No one said you were?

Someone over on FJ was having issues with clutch master cylinders like you and customized one.
