S10 1998 Clutch Master Cylinder Replacement

Just as the title says. Me, having a grand ole time replacing the master cylinder in my junky old 1998 S10 2.2 liter.
It actually wasn't too bad to change the cylinder out, but it was hell getting the system bled again! I had to rent a vacuum bleeding tool from the local auto parts store, and vacuum bleed it from the bottom side of the truck.

Thank you for your video. You seem to be the only person that understands showing each step. So many people skip steps and waste time.

[@urmadhoe]

It's not a fun repair, glad someone else has experienced this

[@jsnjcnt]

Thank you, I was wondering how to get that pin out. Taking the whole line out worked perfectly.

[@eddieorozco580]

Thanks for this great video, I was only trying to figure how to install the clutch starter switch, this video showed me more than I was expecting, thanks again.

[@michaelmyers_dl2673]

In the end of me doing this, my push rod decided to reconnect right when I was about to take the master cylinder out. This obviously caused confusion and I kept going over this video to see if I had missed anything. I spent hours looking around and rewatching this video trying to figure it out. A great, educational video however. Keep it up.

[@toialevao8276]

I wish I could have seen the removing, replacing and installment no matter how insignificant the part may be, it would have been much better to see its entire process. So now I have to go and find another video. I am not even a mechanic but the bush mechanics here have different opinions on why my truck don't start, so I found you. All good by the way...

[@RonaldDaub]

The master cylinder locks with a half a turn there's a square that goes in it and then you turn it but mine don't work right it's not even the same as the last one

[@markbelden6919]

Good video!! Thanks for being thorough

[@omyajt]

Very helpful! My clutch won't budge. Just locked in place. I had replaced the slaved cylinder a few years ago with a clutch change. So hopefully this is the problem. Maybe I'll unhook the line first to see if I can then push the clutch. If I can than it's the slaved cylinder or something inside the bell housing.

[@drestnar]

U SHOULD OF SHOWN ALL STEPS.... THANKS FOR THIS THOUGH

[@GlenWhittekiend]

How did you get that little white tab off the push rod? I can't get mine disconnected.

[@richarddavis9362]

Thanks for your attempts to show anything. Filming the inside of the car under the hood doesn't help one bit, but appreciate your input as to the steps you went through to replace it. How in the world the quick disconnect for the clutch pedal "disconnects" from itself would be the most helpful portion if you would have explained it in the video, but the only thing mentioned was "disconnect the switch located on the clutch pedal". That in itself is the worst part of the whole ordeal so far. I've had flashlights under there and I'm ready to simply snip the terminals for the switch and then reattach them with wire nuts after this ordeal!

[@RonaldDaub]

The switch is junk after you remove it anyway I did the same thing and it works fine

[@RonaldDaub]

I had my master cylinder in perfect but I had to remove it to put the stupid line on it and now it's all screwed up and it don't want to line up and when it does the master cylinder is upside down or leaning I'll figure it out but this is the worst engineered piece of s***

[@RonaldDaub]

I can unhook and hook up the clutch pedal without looking at it

[@josecostoya4316]

How do you bleed this system if the slave cylinder is internal?

[@dylanstansfield1038]

When you bleed the upper part of the system did you have the front of the master as the highest point so the air isn't trapped? And was the pedal just in the up position?

[@donaldschilling162]

How do you replace the clutch sensor under the dash!

[@RonaldDaub]

The square on mine is turn 30° the one I bought is straight up and down and it still won't lock in place after I had to take it out once . Another question is why won't that stupid plug-in at the bottom snap like it's supposed to is the female part wore out?

[@nolifeuchiha1667]

What is the tool called to remove the push rod off the clutch pedal?

[@photondebuger45]

Was the new one made out of metal or were they both made out of metal its hard to tell. I ask because i got a 98 Sonoma and it looks like its made of plastic? And i found an actual metal one to replace it and i wanted to do that.

[@jasonmichelsen8182]

Dumb question: What is the hose running top to bottom on the right side of this video (with the whitish plastic connector at the bottom)? Mine is completely shredded and hanging loose and I can't figure out where it's supposed to go (so many problems with the truck I'm not sure which one it might be causing). I'd appreciate any help you can give!

[@Jon.Rushing]

The white thing is a check valve and that hose goes to the vacuum reservoir in the drivers side fender. you need the vacuum to control your air conditioning and heat controls. My hose had cracked so i replaced the whole thing. If that hose or any vacuum hose is leaking the engine will run lean. It can be a pain to get the hose hooked back up to the reservoir though.

[@chuckh989]

Would anyone know why (98 s10 as well) when I switch gears there is a sound like a kinda loud but maybe just noticeable to me , ok first I heard it going into 2, then 3 , 4 gears mainly shifting up truck runs great no other sounds or anything and isn't every single time ... thanks

[@graftedin1099]

I have a 1994 S-10. I am not sure how to get the line off, as I do not think it is the slave cylinder thats bad, because I found that the line itself had a hole in it down below on the passneger side after I removed the plate by the slave cylinder. Anyways....I really just need to know how to disconnect the lines from up above and below. Is there a pin I need to remove, or does it need a special tool on that year? Thanks, any help is appreciated.

[@CliffsHowTo]

+Grafted In I'm not too sure with those trucks. I know the setup is a bit different. Try searching for it. I'm sure there's info out there.

[@austincorey9396]

Curious what you used to push out that pin? Mines in there pretty good. Tia

[@CliffsHowTo]

A punch and hammer

[@reddbulll7644]

Hey I have a 94 s10 my clutch pedal it's pretty hard and engages all the way at the floor almost does this mean I have to change the master cylinder? Any help

[@CliffsHowTo]

It’s hard to tell without seeing it myself, but that sounds more like a worn out clutch plate to me.

[@jakecruse6206]

what size are the new o rings you put on the line?

[@CliffsHowTo]

If I put o-rings on in the video, it was whatever was supplied in the kit.

[@joeyowens8102]

Q. I have a 1995 s10 chevy.4cyner. 5speed. Cluth is going bad. I removed air from it. That helped alittle. The master cylinder is good! Ok.....does this truck have a slave master cylinder?? If so I can't find it. Could it be the release bearing which is in the tranmission. And for the first time today I noticed it leaking where the transmission bolts up to the engine

[@CliffsHowTo]

I’m not too terribly familiar with the first gen s10, but it does have a master and a slave. I’m not sure if the slave is inside or outside of the bellhousing on your truck. My truck, it was inside the bellhousing. If it’s outside, you will see it. Follow the clutch lines. If the lines go inside the bellhousing, then that’s where it is.

[@Dusty2040]

How do u bleed it out ?

[@zacman11]

how did you remove the neutral safety switch sensor from the push rod..

[@CliffsHowTo]

You know what, that broke years ago, and I had removed that already when it broke... That thing was long gone!

[@ryanwilloughby453]

@@georgeh.7087 try taking the clutch master cylinder cap off and pum the clutch pedal until it begins to stuffen up. If this doesnt work then i would reccomend bleeding it again.

[@All_I_can_say_is_Wow]

I see why you didn't show any of the inside work. Any tips on how to get to that rod inside other than, "Yeah it's easy I did it." ?

[@CliffsHowTo]

I just took a punch and tapped it out with a hammer. Super easy.

[@johnroberts5562]

Have looked for and can't find where the computer is located on a 1998 S10? Can you help me out? Thanks

[@CliffsHowTo]

It is on top of the radiator overflow, on the passenger side of the engine compartment.

[@johnroberts5562]

@@CliffsHowTo - Thanks Bro.. May need to replace it and checking out my ops. Put in a New Fuel Pump & Filter a year ago and it just started acting like it's not getting gas.. Put some BG K44 in and topped it off. I did notice the gas cap wasn't on tight but that wouldn't make it act like that would it? Thanks for the info. I like to know a little about things before I have to take it to a shop. I'll go find it now..... Thanks :)

[@onewheelup]

i was wondering how you insert new rod,i guess just stick it in,also bench bleed the thing it helps get air out

[@CliffsHowTo]

I think it just slides in. Good tip! I didn’t do that... took forever to bleed.

[@ironwill04]

Hello, did you have a problem putting your new master cylinder together? I can not seem to get the plunger in the master cylinder and it came with no instructions. Will

[@CliffsHowTo]

I didn’t have any trouble... maybe make sure you have the correct part?

[@ironwill04]

Cliff's How To Channel yeah i am looking into that now, waiting to hear back from the company. Can you tell me what the travel length of the plunger connected to your pedal is? Does it move 1 inch? 2 inches? Thankswill

[@jaybutton3004]

What is the name/ type of fitting for the master cylinder line to connect from the master cylinder to the slave cylinder

[@CliffsHowTo]

I’m not sure. I just used what was there.

[@jaybutton3004]

@@CliffsHowTo ok cool, I’m manual swapping mine and didn’t come with the fittings so I will just take them from the salvage yard/ parts truck

[@marteloficina]

Hi, nice video, but how you bleed the system?

[@CliffsHowTo]

+Gustavo Henrique Ribeiro you can actually pre-bleed the upper part of the system before reconnecting it. You do this by adding fluid, then having someone push and hold the clutch pedal, and push in the center "circle" on the quick disconnect fitting that snaps into the slave cylinder.

[@marteloficina]

but how you avoid the air mix with oil? And if you add the new oil, how to avoid the old oil will mix with the new oil?

[@CliffsHowTo]

I am not really sure what you are asking... I bled the clutch system this way on my corvette, and had no issues. Sure, some of the old fluid would still be in the slave cylinder, but the object of this video is not to flush all of the fluid, the objective is to change the master cylinder. If you bleed it like I described, there will be no air when you are finished.

[@fernandourtusuastegui5726]

how did you push the pin out of the master cylinder

[@CliffsHowTo]

Punch and hammer

[@fernandourtusuastegui5726]

+Cliff's How To Channel I got it last night but now I'm having problems reconnecting the line that goes back in the transmission. Am I just supposed to push it back in? I tried numerous of time and it just won't click in

You don't want to drive in the dowel pin with the master cylinder in place that's why I had to remove it now it won't go back in right I hate that setup

[@ironwill04]

Hello, Can you tell me how much the push rod in the master cylinder travels where it is attached to the clutch pedal? Will

[@CliffsHowTo]

I really don’t know. And the truck isn’t running at the moment for me to be able to go out and check it for you. Sorry about that.

[@ironwill04]

Sorry to hear about your truck not runnning. Any trouble shooring problems i can help with? I dont need to be running to see how far the push rod travels.

[@kevinlynch9307]

Liking down by transmission how much will it cost me

[@CliffsHowTo]

I have no idea. Depends on exactly what is leaking.

[@nickgonzalez2707]

You forgot the hardest part how to remove the switch and that you have to break the clip to get the rod off the pedal

[@samchacon6088]

It would be nice if you would show the entire process, you just say what you did but not showed it.

[@CliffsHowTo]

I didn’t have a tripod at this time. You’re right though.

[@tammycurtis8853]

Way can't I push clutch peddle

[@CliffsHowTo]

If the connector is not fully seated, then the fluid has nowhere to go.
