SOURCE: ford focus st170 clutch master cylinder

To replace the clutch master, you must remove the under hood fuse box and air filter housing assm, then remove the hydraulic line that goes into the inlet port of the clutch master, then inside the car, remove the hush panel/knee bolster panel from under the steering column, and loosen the boilts that retain the brake pedal to the firewall, then remove the two 10mm bolts that secure the clutch master to the brake pedal assm. Reverse procedure ti install, then fill the brake master cylinder with clean fluid, loosen the bleeder screw at the top of the trans, and bleed the clutch as you would the regular brake system, but never pump the pedal, tighten screw, with foot off of clutch pedal open screw and press pedal to floor, then tighten screw before you release pedal, then release pedal loosen screw, etc. until no more air comes out, it may take quite a few times to fully bleed the system.

SOURCE: how do i bleed the master clutch cylinder system on a 1995 jeep ?

A special pump is used to back bleed the system. If you don't own one then you have to be patient and just keep pumping the clutch pedal until it comes back. It can take a half hour to get it back. Just depents on how much air is inside.

Hi i just put a new master cylinder a month back now today my clutch felt hard and when i put it in reverse heard a broken sound clutch went flat and oil came from the master what can the problem be


Umm...

A mechanical 'breaking noise' doesn't sound good. It's hard to diagnose a problem online without being there to see/hear the vehicle. But .. it may be that your clutch pressure plate has broken/ release/throwout bearing has broken?

It's difficult to see why the master cylinder should leak - unless it was incorrectly fitted in the first place?

Just to check ... The master cylinder is in the engine bay/compartment and is where you top up with clutch fluid. When a master cylinder fails it usually results in no pressure at the clutch pedal, not a leak.

The clutch slave cylinder is the one that does all the work. When you press the pedal hydraulic pressure is sent from the master cylinder to the slave cylinder - which then pushes the release/throwout bearing against the clutch pressure plate and 'disconnects' the driven plate .. allowing you to change gear.

The slave cylinder is the one that does all the hard work - it is located somewhere where engine and gearbox mate together, usually at the bottom right/left. It's usually the one that fails/leaks. It's quite easy to replace..

I don't think it is anything to do with reverse gear. It's more to do with the clutch pedal being depressed - and, I would suspect - something has failed.

The link below is generic images of a clutch:
clutch diagram Google Search

Basically, a clutch is 3 parts. There's the 'pressure plate' which bolts onto your flywheel. The pressure plate is a 'spring'. You depress the clutch pedal and the release/throwout bearing presses onto the centre of the pressure plate causing the 'fingers' - the springs - to bend back and take pressure off the driven plate - which is the link - the drive - between engine and gearbox.

If you have a leak your clutch will not work. This causes a 'grinding/crashing' noise when you try to change gear. The first thing you should do is check where the leak is coming from and do something about it.

The 'noise' that you mention may be due to the fact that the gears are 'grinding' as they try to mesh together without the use of the clutch.

The first thing you should do is check why there's a leak. It's difficult to see why a new master cylinder is leaking unless it was incorrectly fitted and damaged (pipes incorrectly connected..).

If it's the slave cylinder that is leaking - replace it. Easy job.

If Master cylinder and slave cylinder are ok - you have to look at your clutch unit. A clutch is always replaced with 3 parts ... throwout bearing/pressure plate and driven disk.

Why is my chevy s10 gears are getting harder to put in ?


I would look to see if the clutch master cylinder is low. It is smaller but like the brake master cylinder. If so check to see if the slave cylinder on the bell housing is leaking or the master cylinder is leaking. Low fluid or no adjustment will make it hard to get in gear.

Check your clutch slave cylinder.

Won;t start while clutch pressed but will push start


The clutch master cylinder must have gone out, the seals in it have failed. The clutch master cylinder (next to the brake master cylinder) gives you hydraulic pressure so the clutch pedal can operate the clutch.
You can buy a new clutch master, a rebuilt unit, or yours can be rebuilt with new seals. Save time and money and buy a rebuilt or remanufactured unit. Once installed, you bleed the system down at the clutch slave cylinder, mounted on the transaxle.

Clutch slave silender has no pressure


Depending on the make and model, could be a faulty clutch master cylinder.

Wont go into gear


Did any fluid come out? It has to have fluid reach the slave cylinder, and when bleed valve is open and clutch is pressed, fluid should squirt out. Open the valve and pump the clutch until fluid is forced down into the slave cylinder. Keep topping up the clutch master cylinder so it won't run dry.
Post back if still having problems. There is a tool at auto parts stores for pressure bleeding brake lines and clutch lines. It forces fluid into the lines by pressure. If nothing works, your clutch master cylinder may have failed. Take the line off at the slave cylinder and see if the master cylinder is working to push fluid through the line.

Cant find the clutch reservoir on my audi a4 1.8 eastate r reg..


The Clutch Master Cylinder is located on the firewall inside the engine bay, and usually next to the brake master cylinder as the brake and clutch pedals are usually very close to one another. The Clutch Master Cylinder is responsible for transferring the clutch pedal pressure hydraulically to the slave cylinder to release the clutch. You can tell when your clutch master cylinder is dying or needs repair when you depress your clutch pedal and it slowly sinks to the floor and does not return. Since the entire system is a hydraulic one, the master cylinder also has a reservoir that holds the fluid used in the clutch hydraulic system. If you decide to change the clutch master cylinder it is a good idea to also get a clutch slave cylinder at the same time, as both units typically fail around the same time. When replacing your master or slave cylinder, its always a good idea to flush your entire system to prevent water buildup or air pockets from being present when you are driving. Also always keep an eye on the fluid in your reservoir, dirty fluid may mean that the internal seals are allowing dirt and contaminants into your master cylinder.

Fitted new clutch and slave cylinder in 2.5 v6


crawl up under the dashboard & look where the clutch pedal rod goes through the firewall. look for traces of brake fluid at the rubber boot of the rod. a clutch master cylinder normally will leak to the inside of the vehicle & down the firewall when it fails. Replace as required & bleed clutch system using the bleeder valve that should be on the slave asy.
