Clutch pedal to the floor

[BRUN]

anyone had any issues with the clutch pedal going to the floor, its happened on mine and ive managed get it to the garage, no sign of any obvious leaks so its a case of trying a master cylinder probably and hoping it sorts it, or the box having to come off to check the slave and replace it anyway with a new clutch

 

just wondering if there is anything common to look for before it costs me £££

Yep, mine does it when reversing with our caravan. There have been a few reports of premature clutch failure on manuals used to tow.

I have never towed with mine, and to the best of my knowledge it hasnt been used to tow before I got it, no evidence of a tow bar ever being fitted etc

 

new master cylinder is now on, and initial short road test, it seems fixed, but time will tell and longer journeys

How much was a new master cylinder?

It won't be and time will indeed tell.

used an LUK non gen one, £211 fitted with new pins that hold it in and bush on the end of it, but I work in parts so do get things a bit cheaper

 

they flushed out all the pipes and there was bits of crap in the fluid somehow, im thinking maybe a seal had deteriorated ?

why not ?

Because the air causing the problem would have almost certainly been from the slave cylinder and trapped in the void below the bleed thumb-turn.

 

Wwhilst I agree 100% with replacing the master cylinder first, doing so involves bleeding the system which will give  temporary respite, I hope yours is the exception but I expect the symptom to reoccur and that will probably be with a change in temperatures, I cant recall now if mine reoccurred in Spring or Winter.

hopefully it is the exception, ive only done a few miles so far, probably about 10, but so far so good
