Vectra Brakes were down to the metal.
New disks and pads fitted,
pedal spongey.
Bled brakes, got some manky old fluid out, and some air bubbles.
Pedal is still spongey, you can pump the pedal up each time you get in the car, and once brakes pressed, pedal does sink further.
Any ideas anyone?
Cheers

Did you let the fluid out the bleed nipple when you pressed the pistons back in?

Ow dear.....ow dear ow dear......ow dear ow dear ow dear ow dear......
Right, get in the car and press teh brake pedal righ down, as you lift your foot off get somebody to hit the end of the brake master cylinder with a mall....oh yes,ok, lets start again.
Get Ljay to press the brake pedal all the way down and as she quickly lifts her foot off hit the end of the brake master cylinder with a mallet..
I asume the padswere fitted correctly?
Rubber backed pad sections against the caliper frame and metal to the caliper piston?
All sliders are free?

Father in law and me this one.
Different set up to the omega, you can't get em the wrong way round, clips go into the piston, and bloody 7mm allen key to secure calliper
What set has 7mm? 6 - 8 everywhere >:(
Is this the inverted seal I've heard mention of?
-
What sort of strength hit?
-
Mine has 7mm....only shite Halfords sets have key sizes missing
-

Like your hitting a chisel....repeat it 5 or 6 times

What actually happens? Does it flip the seals or something? :-?
-
ok, is that 5-6 times hit per pedal release, or whole procedure 5-6 times?

I think this is what I'll have to do eventually on my Omega.

Thought I read about it somewhere years ago!
Which seals does it flip? ABS pump or Master Cylinder? Im assuming Master Cylinder since your suggesting hitting it! Hows that fix it then? (Just been nosey! ;D)

You know what Andy, I wonder if thats the problem with mine too come to think about it?
I always put it down to it been a big heavy auto though? they work fine, just a bit spoongy! - Got used to it now, and to be honest had forgot all about it until now! :-X
-
Would you do this with the engine running or not?
-
Engine off

:D
Seems to have done the trick
Waiting for the results from a test drive......

Now let that be a lesson to you....heed my advice and warning in future and forever bow down to my greater knowledge! ;D ;D ;D
Also be aware I have just saved you the cost of a new master cylinder for the sake of a good banging with the father in law!

Fankoo, Uncle Mark to the rescue again :y

'll have to try the mallet trick. Large or small plastic headed or leather/copper Thor mallet?
-
How many of the master cylinder seals reverse? Anyone know?
I've just tw4ted judiscously tapped mine while SWMBO pressed & released the pedal, and although I've only driven the car around the block I think it's made a positive difference :). I'll bleed the brakes in the morning.
If seals have been flipped in the master cylinder, would it not be a good idea to get a replacement seal kit for it? .... assuming they're available. :-/

Father in law has rebuilt master cylinders before, but there doesnt seem to be a seal kit

..... but there doesnt seem to be a seal kit
That doesn't surprise me :(. I'll see what they're like tomorrow after a bleed. :y
-
He is saying the pedal is lower than before, dont know if that is realted to this, or if anything can be done about it?
-

My Halford set seems to have lots of missing sizes. Found a couple of them tidying up the gargae though ;D
-

Should come up as the pads bed in....or the adjusters are a bit sticky.....or there is some air in the system.......or hes gong senile

1 or 2...depending on how many you reverse.
You used to be able toget master seal piston kits with the seals on but, to be honest, since british car manufacturers dissapeared, I cnat remember the last time I needed to do one (I still do old triumphs, Metros and such shite occasionaly!)
-

Thanks Mark.
Are all master cylinders the same? I saw a couple the other week on eBay that said they were for a 2.6/3.2 Are they different from other (V6) cars?
I might look at swapping it for one from a newer car

Cant say I have ever looked at the compatibility......as they dont fail.
They only ever did in th past because BL used shite castings + seals and people didn't change the fluid resulting in corrosion and seal failure.

......as they dont fail.......
Unless you manage to reverse the seals ::) I'm reluctant to remove mine at the moment to look, I need it next week to pull (and hopefully stop) my caravan. :y :y :y :y

Well do the mallet trick...its not like reversing the seals does any great damage to them

I did this morning, and it seemed better, but I couldn't decide if it was my imagination ::). Like I said, I'll bleed 'em in the morning & go from there. :y

Wonder if good old HTS could come up with the seals if you need some Andy.

An excellent idea John, I bet they could. Which might be another reason to get A N Othermaster cylinder to strip, it'd save having the car in bits for a couple of days. :y :y :y
I'm hoping that a good bleed tomorrow will sort them out. Brake fluid bought on the way to work this afternoon. :y

Yep that's what I was thinking, get one off a scrapper, recon it then its just a swap over hoping you don't get air in the ABS module.

Just bled it. So far so good. The pedal seems a lot firmer, and doesn't appear to yield under pressure. :-X (Do we have a smiley croosing his fingers? ::))
Why are my calipers all 'orrible and rusty? :'(

Probably because you use orrible acidic alloy wheel cleaner

They always have been :( . I'm blaming the previous owner! ;D ;D
I might have to see about their replacement some time when I get a bill free month. It might be a while ....... :-?
