icon9.gif  Clutch Master Cylinder Issues - WHY!! Sat, 03 April 2004 07:09 Go to next message
Hey guys/girls,

Have just found my clutch master cylinder leaking inside around pedal box. This is annoying because I replaced it in late December '03 when I replaced clutch Shocked . I'd just like to know is there anything I could have done that has wrecked this. I have the clutch adjusted so it starts to contact flywheel after only about 1 inch from the floor, Taking up this early, that couldn't have caused this to happen could it? Shouldn't when the clutch pedal is fully released the clevis and piston will be at start of stroke..i.e resting on the end stop as when master cylinder is off vehicle with no force on it.

The brand is:
"Top Performance" in blue box with a couple of elephants on it..I paid $85 from a local place that usually sells decent gear.

Anybody had similar experience..it is going through a fair bit of fluid, I wonder if it is still under warranty

How much warranty do these parts usually have?
So where the clutch pedal releases to is dictated by the piston at full retraction. I made sure I had a little freeplay there.

Thanks for your post MRDOHC..makes me feel a bit better

My guess is that it was sitting around for a fair while before you bought it Evil or Very Mad

And the seals gone hard.. yeah that sounds very possible, you think for corollas they'd move quite a few of them. I'm going down in the morning to show it to them and hopefully get another one. I just don't want to replace it again and find the next does the same after a little while Mad . Anybody used these "Top performance" with elephants on packet. They sell clutch and brake parts, and install so you wouldn't think they would sell crap. Confused

Cheers

'Top Performance' and dancing elephants on the packet? Sounds like a hugely reputable and professional operation to me! Shocked

That last post is killing me squall!! You're right the elephants don't exactly help build confidence in the product. Maybe I should ask for my money back and go elsewhere, they probably won't do that though..I may have to dance with the elephants again! Hopefully it will work out better this time around.

Have you still got the original clutch master? If not, get your money back from the non-genuine master cyclinder and go and get a genuine reco kit from toyota - it shouldn't cost you more than $40.

The mc may have corroded and may be pitted. Did you inspect it for corrosion and / or hone it before re assembly?

Mine went on me mid last year as well, i replaced it with a PBR one, cost me $110 for the celica.Worth it coz its not leakin everywhere anymore and it actually has a better feel than most others that ive driven (probs makes no differnce tho) but at least they're a respected and known brand. And those reco kits cost like 150 from toyota.

$150 for an overhaul kit? I paid that for a complete master cylinder from toyota. The last clutch overhaul kit cost me $39, and that was the genuine article.

Thanks everyone. I just finished pulling out the MC Smile , they said they'd replace it but only after they checked mine was leaking..so I'll have my car offroad tommorrow while I swap it and install. I don't know if I could get money back. I do still have the original toyota one, but the problem with that wasn't that it was just leaking, when I installed new clutch we couldn't get rid of the air in system...we traced it to MS, so I'm not sure if it is beyond repair.

PS The one they're giving me this time hasn't got elephants on the box..maybe they had probs with that brand Confused . There's a shitload of fluid around the pedal box, and by the way AE82 pedal boxes are a bit of a prick to work with. Gave the GE an oil change while I was dirty so hopefully will have it back on road tommorrow night.. Getting lifts to work with mum ain't that cool! Shocked

Thanks for helping and listening to my fairly trivial prob

these things are assembled in a factory by morons, not an operating room, and the factory type stuff you'll find in any & every THING that you purchase would make you puke.
you've got to take it apart if you want to know that it is right.

the initial oil & filter change on new cars isn't becuse the oil is "worn out" or from cylinder & crankshaft stuff. it's to get rid of the factory stuff that should have been in the dustbin instead of the engine.

Put the replacement one in last night Smile . They do seem pretty crap quality Sad , hopefully this one will last but I haven't got that much faith. When I took it back the guy was trying to tell me that I used old brake fluid as there was some residual fluid there that looked dark and said it was gritty. He rang me back later as they decided to pull it apart and have a look, apparently when they assemble them they put some assembly fluid in there so that it doesn't corrode or seals get hard as they may sit on shelf for a while. Most of the others he had seen have clear assembly fluid.

Nobodies had probs with the Castrol response dot 4 have they..that's what I've been using.

I think I'll pull apart the old toyota MS (not sure if original or not..has made in Italy on cap..so maybe not)
