Thanks for the ideas guys, I will bleed them again, yes genuine fluid has been swapped right out and then some. The next thing on my list will be to swap the servo! I have just gone offshore for 3 weeks so will report back when done, in the meantime if anyone has any other suggestions please throw them on the table! Thanks Guys

Update This weekend I got a pressure bleed done to the brake system with no difference? So I am head scratching now, before the pressure bleed I changed the position of the rod in the servo as I was told extending it a small amount would fix it, so tried this in 3 different positions with 3 lots of bleeding. So the pedal still goes down a long way before the brakes work but if you lift off and pump a the pedal twice the pedal goes firm and the pedal works at the top. So any suggestions to check would be welcome. Thanks Greg

Good How to! I pretty much did the same to all mine the other day when checking the calipers were working correctly!

Hi Steve There was no bleed screw on the ABS Pump but I also bleed the from the 2 feeds into the ABS unit three times, once with the Engine running as well. I did do a similar thing to what you suggest, i actually clamped the brake line then removed said calipers one at a time then fitted brake line to a blank block which i drilled and tapped out. I also checked the calipers for movement on the bench with an air line under light pressure all fine and free and moved back in with the lightest of pressure. So I am thinking it must be something else? But thanks for the tips and advice! Do you know anything about the brake booster unit I keep reading about? Thanks Greg

Hello Steve Thanks for the welcome! The Clutch and bits where done by Lexus but its been about 2500 miles since and not sure they would be interested? It started to happen at about 2200 miles the clutch judders when cold and now and again you can hear the thrust bearings, also when cold if you have your foot all the way down on the clutch and select 1st gear the car jumps forward a tiny bit. Of late it has become a bag of problems, and it is seriously making me think of never getting another Lexus, it's not like it even had a hard life? on 78K Thanks Greg

Hello Was driving along the other day, went to brake normally and found the brake pedal went soft and traveled a long way down before the brakes came on, luckily they did before my trousers changed colour. At the time it felt as if fluid was passing the first stage of the master cylinder and I could also hear a short pulsed pump noise which also seemed to come back through the pedal. Got The car recovered home when getting it off the tow truck noticed the brakes did it again they work but the pedal is soft and goes down a long way before it works. So decided it was the master cylinder after the recovery guy said that was what it is as well. So ordered a new one from Lexus at the cost of over £300 and fitted it, used the check plate and the rod needed adjusting less than 1mm, replaced with Lexus fluid, bleed from master cylinder first then rears and fronts, only to find it was no better? bleed with engine running, again no difference? Has anyone had this happen or heard of anything similar? I also whipped of all the wheels and checked all the break calipers all are free and working perfectly and lots of meat left on the pads. The other thing I find strange is that all through out this no lights have come on? If anyone could shed some light it would be great thanks! Greg

Hello to you all! I have a 2006 IS250 Sport, Black, Factory tints DVD player and screens in the headrests with head phones for the kids, now covered 78K. In the last year alone it has had a few issues, one the clutch and DMF were replaced by my local Lexus dealer and its still not right? Anyway I was searching and found this place, I did not know such a place for these cars existed, I look forward to chatting with you all. Thanks Greg
