Hey guys recently went to drive my truck after just parking and my clutch went strait to the floor changed the master cylinder today and it’s doing the same thing.would anyone happen to know of a high quality slave cylinder I could buy.I’m not a big fan of luk slave cylinders considering the one that’s on the truck now was replaced 2 months ago and is spraying fluid everywhere now thanks in advance

Use luk only only only

Luk is the oem part
I will not install a slave cylinder from any other brand
To remove the transmission is a lot of labor so you must use a good slave cykinder

Other brands can last weeks or months not 150k miles like factory


You should replace the master and slave at same time and you should know how to bleed the system outside of the truck before Install
Good time to consider a new clutch or at least new driven disk if the rest of the clutch is luk abs fairly new

Luk

Replace the Master Cylinder at the same time.

Watch out - don't lose the very small o-ring when interconnecting the clutch master to the slave.

I just replaced everything about 6 months ago with luk when my trans blew a couple weeks ago the clutch and everything looked fine and the slave cylinder yesterday just quite working and it’s luk brand maybe just a defective product? Where do you guys order from,rock auto,Amazon any good with there luk products?

Start simple.

Have you checked that the air bleed nipple on outside of the the slave cyl is tight?

It's a quick check, Easily accessible by sliding under your Ex, no lifting required.

Bleed Nipple is on the drivers side of the bellhousing.

I've never had an issue with LUK components, and I had the entire clutch assembly replaced twice in 16 yrs of ownership.

In fact, BOTH flat-rate transmission shops that I brought my self purchased clutch components to informed me, before working on my truck with my self bought parts, that they wouldn't touch anything but LUK in order to warranty their labor.

I bought everything LUK Brand (Flywheel, Pilot Bearing, Clutch, Pressure Plate, Master and Slave Cyl & Throw-out Bearing) both times from Rock Auto.

BTW - Hopefully you bought NEW FLYWHEEL (as opposed to resurfacing) along with a NEW Pilot Bearing.

FWIW - This particular clutch system is a "throw away" when they wear out - Your Mileage (and others) might vary.

Yes I narrowed it down the the salve cylinder because after dropping the trans and took the cylinder out it was leaking fro 2 seals my question is why has it failed after only 2 months of driving if there company is so good

Not sure why yours started leaking
Is it for sure a luk? It should say on the base

It should be covered under warranty if it is only 2 months old

That stinks!

If it’s any consolation when I was much younger I had the 5’speed out of my bronco 2 for clutch issues 4 times in one summer

You should replace the master slave and line all at the same time, yes even if they are only a few months old, especially if you think you may have fake luk parts

Rockauto sells the parts

As far as I remember, LUK brand slave cylinders are embossed in the plastic with the trademark LUK (within an oval) - it's pretty small.

Then again, I've always ordered from Rock Auto, and there's never been a doubt to product authenticity.

With regards to your trans being out 4 times, something's amiss - but I digress.

Good Luk ;)

It is a very small stamp in the plastic
You maybe just missing it
Or
Counterfeit part / bad seller

One of the reasons I use rockauto summit jegs speedway car parts.com and many others Before I choose eBay or Amazon and then I look closely at seller ratings and reviews

I agree Im not ordering any more parts from Amazon or eBay the other slave cylinder came from Amazon and failed in 3 months but was supposedly “luk” but now I just got the new one from rock auto and don’t see anywhere on it saying luk just part number if anyone can confirm #db07rn602a

I got a Luk clutch and slave from rockauto a couple years ago and never installed it.
I just pulled it out and looked to see if it says Luk anywhere on it, nope! Just on the box.
Does your box say Luk?
