Update - Clutch Pedal Sticking or is it Shot...

Post by Harrymonk »

Coming home the other night and my clutch pedal wouldn't come up off the floor, managed to bring it up with my foot, but when i pressed it again it sinks to the floor. Sometimes the pedal is stiff and comes back up, but other times i can press it sticks to the floor.

Have done a search and can't find a similar issue, over on the other forums people have detailed a recall on the peddle bracket?

Would this be the clutch bracket? or slave/master problem?

No mention of brackets?

Is there anything I can look for on the slave and check or is it simply replace it as first course of action?

Not a bad DIY there Pete :thumleft:

From experience of TWO failed clutch slaves on RX-7's (the same setup pretty much), this was the exact same symptom I had, so the most likely cause, so I'd start there. Maybe look for leaks in any of the visible clutch lines first though, should be obvious if there is fluid leaking.

Much easier to see the slave on an RX-7 to diagnose and fix though!

My guess would be a hydraulic issue, either master or slave cylinder.
It's not unusual for the clutch line to be forgotten when the brake fluid is changed and this can result in internal corrosion from very old fluid.

When you've got it sorted then this link may be handy to adjust the pedal action
viewtopic.php?f=6&t=78426&p=1183402&hil ... l#p1183402

If the bracket has cracked, then take a look at this thread
viewtopic.php?f=30&t=38897&hilit=clutch+pedal+bracket
only problem being that the supplier no longer produces the bolt-on.

However, good used replacements should be available from our trusted suppliers (e.g. BigPete) as it's not as common a failure over here as the US guys would suggest.

I did have this happen a few years ago a couple of times - on both occasions it was particularly hot and I was in stop-go traffic for a very long time. Once I was able to stop and let everything cool down it was all fine again and, so far, hasn't happened again. I got the impression back then that it was probably the slave or master cylinder and thought I would get it sorted if it ever happened again ... so far so good [-o<

There is a common problem on the early cars where the clutch doesn't fully disengage when very hot.

This was caused by a production issue and is cured by replacing the slave cylinder.

Mine does this if stuck in stop-start traffic on a hot day - which hasn't been an issue since we moved to NI ;)

I have a Pagid cylinder waiting to be fitted but it's not a priority atm.

My experience was on the last stretch of an enthusiastic drive home late at night when it was quiet, didn't manage to get out to look last night as it was chucking it down but will probably order a new slave and start there.

Two parts of the change are frustrating- attaching the hardline (attach it before you mount it), and bleeding the b*****. You'll be wanting a friend for that.

Okay so on further investigation the peddle and slave cylinder are the least of my worries. Clutch squealing and when pressed sounds and feels like a bag of bolts rattling around in there ! Can’t engage hear as it feels like it will smash to bits.Is this familiar? Sounds like clutch or at least the throw bearing?

Might be the end as cost to sort outweighs what I will get back when looking to sell in the summer 😕 sad times

I think that's a failed clutch release bearing.

New clutch defo,as above it sounds like your release bearing is shot.You can get an Exedy clutch from MRP for circa 300 quid.Mine is giving me a bit of bother recently too now that you mention it,she's in this morning having a few jobs done so I told my guy to check everything clutch releated but i fear mine is on the way out too.

Mines an Exedy and has been on the car for four years so it's probably time to replace.I'm not sure if MRP are still giving us a 5pc discount because when I entered the code at checkout yesterday it didn't accept it...

Thank you, thought it was, unfortunately its not financially worth doing as will be selling up in the new year and wont see the money back in a sale so unfortunately I will have to go down the breaking route.

Unless you've got lots of space, time and tools, breaking a car is a major headache and almost never makes anything like as much money as you'd expect. While there's a market for some used parts, so much of the car is either so reliable that there's no market for used, or the parts are so unreliable that people couldn't take the risk of used. My bet is you'll have more than half of the car left after a year.

A half-broken car takes up 3x the space of a complete car and it's very easy to damage parts in removal or storage.

It would be cleaner to either fix the car and sell it as a runner, or not fix the car and sell it as "spares or repair" - recognising that it needs a clutch.

This is the quandary ! Wont be fixing as around £600 for a new clutch all in (Have to get the car transported to garage) on a car that will be worth £900 if I'm lucky when complete I wouldn't need to sell much to make more. You are right though given the headache, although I have space and time I think a spares or repairs would be the way after returning to standard then selling mods and extras that i have left after. Its a sad decision but for what I paid I've had a lot of fun.

Could you not do this yourself, if you have the space on a drive there is a lot of guidance here that could help you do this at home, i'm sure its simple tools for a clutch change? Saves giving up on the car you love

if you can do it yourself, need to do it on a tight budget and the car doesnt have TOO many miles on its current clutch, it would fix it if you JUST changed the release bearing.

If you've got the space, tools and skills to break a car then replacing a release bearings should be easy.
