182 205 306 rallye
Ok I have had the 182 for around a year now. The mrs normally drives it so when I do drive it I do notice a difference with the brakes. I have always thought the brakes were s**te compared to the 205 gti and 306 rallye I normally drive. Of late the pedal travel is quite a lot before anything happens and then its a really hard pedal. The car does stop but they are sh!t. Its had new disc and pads all round just before I bought it. When you stomped hard on the brakes the abs never felt like it kicked in and pulsed through the pedal like it would on the pugs nor does it lock up.
I fitted new o.e pads a while back and it made no difference. Shortly after that I pressure bled the brakes using a Sealey pressure bleeder ( set to 10psi ). I have bled lots of cars so had no issue doing this. The fluid changed colour to the nice fresh stuff as you would expect. At first the rear n/s would not bleed. A quick prod down the nipple unblocked it and happy days. I drove the car and again no difference. So re bled them etc and still no difference.
That was around six months ago and like I said above they have got worse since. The servo seems to be working fine as when you pump the pedal with the engine off it goes hard after a few pumps and holding the pedal down when you start the engine it sinks down. I drove the car last night in the wet and gave the brakes a good what for and the abs again would not activate. I have just re bled them again tonight after spending all afternoon searching on here and the most common results being bleeding and checking the vacuum pipes. Before I bled it I gave it a drive and really abused the brakes to get any air moving. I did notice the abs kind of kicked in this time which is a first. I also checked the vac pipes and they looked ok with no signs of any hissing etc. As the servo seems to be working I would guess that ruled out the one way valve too?
To sum it up they are still sh!t
So this has made me think of the master cylinder to be a fault. As above there is a lot of pedal travel that has no feel before it feels like it hits a stop almost. With the m/c sitting in the most stupid place, all that heat and extra brake effort can not have done the seals any good? I have been advised that decent pads such as Ds2500 and Brembo hc discs will improve things but I want to fix the fault first not mask it. I have 2500's on the rallye and am wel impressed with them so I have no issue forking out for some.
Now. When I have searched for master cylinders for the car they seem to list two sizes for the 172 / 182 with abs. 20.6mm and 22mm. Which one is fitted to the 182? I cannot find an anwser on here. Also I have read on here about the dredded air in the abs pump. If its such an issue how do you bleed the system post master cylinder change? I would get fluid in the master cylinder before fitting the pipes so to reduce air intake into the system, but you are always going to get some. Is it just a case of lots of bleeding and fluid and in the correct order and hope for the best?
Thanks for taking the time to read my essay and thanks in advance for any help you can give.
