Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / November 2005golf clutch fault... slave or master ???
Hi there, Volkswagen Golf P Reg. TDI The clutch pedal is getting closer to the floor making a gear shift difficult / noisy. I can however pull it back to nomal position... but it will slowly over weeks go back down again. Is It liable to be the master or slave cylinder that's at fault. Probably both should be done ... but the master cylinder is pricey and difficult to fit, in comparison to the slave... ...any ideas ??? > Hi there, > [quoted text clipped - 14 lines] > ...any > ideas ??? Well, you don't mention how many miles you have on it, or when the last time you changed fluid was, or even if it is low, but if it isn't slipping, then it probably isn't the clutch. The master cylinder is for your brakes and the slave cylinder is for your clutch, so if you find it hard shifting, you may want to flush out the fluid out of both and replace with new fluid and also make sure the slave cylinder has enough pressure in it. I had a similar problem with one of my vehicles where it was hard to shift... the pedal seemed worked fine and all, but once in a while the shift lever was hard to take out of and put in gear. My mechanic did just as I am mentioning here... and all has been fine since... good Luck Fwed I know of no way to test them individually, so you should replace the slave. I already agree with you Misterbeets because it's the cheaper/easier option... BUT... significantly the symptoms ...whereby the pedal edges it's way to the floor are indicative of a tired return spring in the master cylinder... so...I'll bite the bullet and do the master first. FACT : 1. Hugo... There is no rust around the slave. I agree this would have been important. (and obviously none on the master.) FACT : 2. Be careful what you read on the "net"... fweddy bear reckons the master clutch cylinder is for your brakes. tut tut... FACT : 3. screwballtarius97 .... and 98, and 99, ....... > I already agree with you Misterbeets because it's the cheaper/easier > option... [quoted text clipped - 6 lines] > > FACT : 1. Hugo... There is no rust around the slave. The rust is INSIDE. You can't see it until you disassemble the clyinder and look down the bore. OK buddie I've changed tack its gotta be the slave...as specially as a volks specialist who I priced the parts (for the 5th. time) has said that the slave will mormally go first... > OK buddie I've changed tack its gotta be the slave...as specially as a > volks specialist who I priced the parts (for the 5th. time) has said > that the slave will mormally go first... That was initially my diagnosis too....how bout that sports vans???? lol Fwed > > OK buddie I've changed tack its gotta be the slave...as specially as a > > volks specialist who I priced the parts (for the 5th. time) has said [quoted text clipped - 3 lines] > > Fwed Fewd, the slave cylinder is down at the transmission, the clutch master cylinder is up beside the brake master cylinder some place.

Fwed Let me get this right.... You can physically reach down and pull the pedal up and it will be fine for a while???? I would be under the strong opinion you are missing a spring on the top of the pedal inside the cab. That would mean the weight of the pedal is bouncing on the small piston spring inside the master and holding on the masters piston's seal for a while. Eventually the fluid is getting past the seal so the pedal only travels a short distance and the clutch will start to grind and not want to go into gear. I think this might mean you need a new master 'someday', but only a top pedal spring today.

Mike ...the theory about the pedal spring in the cab ...someone else suggested that to me tonight ... all will be revealed tomorrow night when I get the car to look at. I would be interested in hearing.

I had the clutch pedal return spring on my Honda break once (made a sort of a "doink" noise when it snapped). The pedal worked fine without it except it exhibited very little resistance to foot pressure. Really threw my clutch/accelerator timing off. I did not expect that the pedal spring would have had that much effect on pedal pressure, but it did. It cost $3 and took all of fifteen (fiddly) minutes to replace. Let me get this right....

I think this might mean you need a new master 'someday', but only a top pedal spring today. NO simple explanation yet... But It's ironic that you suspected a missing spring from the top of the pedal because that's almost the situation I've found... I say almost because there is a return spring fitted which is very strong looking and lubricated and seems to be working ok... But at the top of the strange shaped pedal there is a linkage type connection which has nothing to it , maybe it's not always used. But the pedal is definitely under spring pressure. I'm gonna leave well alone and see if we get the decent weather before it goes wrong again ... we have ice and snow outside now and my garage is too cluttered to get in with the car. > Hi there, > > Volkswagen Golf P Reg.

The first P-Regs had a clutch cable that was notorious for pulling through the bulkhead. > The clutch pedal is getting closer to the floor making a gear shift > difficult / noisy.

Hi last week my ford tarus start injected fluid everywhere so I pulled over had it tow and so called repaired being told it was a $19.00 connection part that caused the problem. Later in the week my car wouldn't go over 20 mph without rev up to 4,000 rpm. I was then told by mechicanic to pay 1,330.00 for rebuilt trans or $4,000 for a new one. I ask him was he crazy that all the car is probably worth. After going to another trans place I was then told I only need 2 sensors and pay $75.oo for labor and this could sovle the problem but since they fix it my car is had to steer in reverse what now -- screwballtarius97 > Hi there, > [quoted text clipped - 14 lines] > ...any > ideas ??? The slave usually goes first because it is the most exposed to road dirt, salt and moisture. |
