Bleeding brakes!!

I understand there is a 'bedding' in period when changing pads, I also understand that putting new pads on warped/scored or worn out discs is stupid, what I don't understand is how after bleeding I had a good pedal for a month and now it's getting soft again. I'm sorry but if what your saying is right then once the pads are 'bedded' in then I should have a good pedal therefore the softness should be getting better if anything.
What ****es me off is garages trying to fleece customers for new rotors/discs when all that's required is a bedding in period.
Where do you work??

Firstly as I said in the last post I don't think this is the problem your haveing but in your original post you stated you had new pads and I was makeing you aware this can cause a low pedal. As for fleecing customers I'm sure some places do. But we won't warent our work for NOISE if the rotors are not machined or replaced depending on what's required. And the law states rotors on or below min thickness must be replaced. And no I'm not telling you where I work but brakes is what we do

Here's good example of what most ppl think is an ok rotor and just slap pads in and wonder why the pedal goes to the ****ing floor

And I've had plenty of customers argue and call us ****s and say we are ripping them off because to them they think a rotor like that is a ok I see it day in and day out

I agree with you that some people wouldn't know what a good or bad rotor looks like, luckily I do. I have never seen a pedal go soft over the course of a month because of new pads on old rotors (I'm not talking worn out or scored I'm talking rotors on there second set of pads!!) Having to deal with the public is something I don't envy you, I did for awhile and know there are a lot of people that know a lot about **** all!! or try and scam free work or parts by kicking up a fuss.

Long shot. It seems to me you may be getting air into the system. Where air can get in, fluid can get out so take a look for any signs of seepage on any of the connections.

This works for diesel engines which wont start if air is in the system, so maybe it will work for brakes too.

how certain are you its not the master cylinder recirculating untill you get to a certain point in the piston or a certain pressure level?

Hey Ned, where did you get quoted £180 for the master cylinder? I have a 90 of the same vintage and here in Perth also. Having the same problems with mine and I suspect a leaking M/C.

I've used my Nanocom Evo on power bleed, with some improvement, but still not perfect!

Paddocks are £190 plus delivery which shouldn't be too much, I think they get them direct from LR. Main dealer in Perth quoted $1000+ and over a week to get from over East?? Doesn't make sense to me at all?? I'm leaning towards MC as ABS modulator doesn't bare thinking about :eek:

Sweet as long as we know where we stand here and dealing with the public is the worst part of the trade

Master cylinder ordered from Britcar - it'll be hear from the UK faster than it would if it came ex-east! I'll keep you posted!

And this could also be the problem but bloody hard do diagnose even when it's in the workshop but normally with light pressure it will just creep away maybe to the floor or half way depending what circuit is by passing but it won't be low all the time
