*** Cup owners - Brake Bias Valve ***

[Rich-D]

This is VERY important people...

As you probably already know, there has been a lot of talk on here lately about a problem with the brake bias valve on the Cup (maybe 172 as well?!) and it could potentially cause an accident!!!

There "should" be a link between the brake bias valve and the rear beam, which alters the braking bias of the car, but in some cases this is missing.

I just checked mine to find that it is not there and I am on my way to Renault this afternoon, to get it sorted out. With the weather now being cold, damp and frosty theres no way you want the brakes to be faulty...

Please check your cars for this fault ASAP and if it looks like the pic below (i.e. no link) then get yours to the dealer and get it fixed!

Do not ignore this folks...

With the exception of a brake limiter valve altogether as you have ABS mate...

 

[Dust]

I just had a look underneath...and mine doesnt have one of those bars. Outraged.

 

[TheCake]

Outraged x 2. Me neither.

We definately need something from Renault about this. As my local garage think theres nothing wrong with it!!

 

[jon_r]

Im gonna look a right prat outside the office, but ill go and have a look in a bit.

 

[jon_r]

Dust or Rich, does yours feel funny under braking then?

 

[Dust]

Yeh back end goes a bit light.

Just spoke to my renault dealer. They seem to think the Cup is not ment to have one. Normally larger cars like estates and vans have them but not the Cup. And because Renault have not recorded this as a fault...they want to charge me to fit this. What should i do??

 

[jon_r]

OK mine doesnt have one either. And i just got laughed at by the guys in the office. Are they meant to have one?? Are you sure?

 

[jon_r]

But the back end should go light under braking??!?? As 75/80% of the braking is done at the front.

 

[Dust]

My dealer says they are not ment to have one...but i doubt them very much. Has anyone been in touch with Renault UK?

 

[Dust]

Can someone post the number for Renault HQ. I need to get to the bottom of this. Cheers.

 

[jon_r]

We need to ask Mike on the other thread his advice, he seems to know a lot.

 

[Dust]

Renault Customer Service - 0800 0723372

Renault UK - 01923 895000

 

[D-CUP]

Id wait until Renault themselves make an official statement about this. If everyone who owns a CUP says theres doesnt have the part then thats how they should be.

 

[jon_r]

Yes i mean someone with a Cup on here must have the part.

 

[Chris n nic]

Is there actually anyone who does have this part? My mate reckons the missing bit would be there instead of the valve(as with the 172)

 

[McBunny]

i would have thought it should still have one even without abs as its there to sort out the amount of pressure needed to compensate for large loads in the boot so should need one no matter what id have thought but could be wrong

 

[Dust]

hehe on the phone to Renault Customer Service now...they said because my dealer does not think the car is ment to have one of these parts, they will not replace. Dealers will only replace a part under warrenty if its ment to be there or broken.

Now, for a re-call to take place..the network of dealers must report this fault to Renault UK and the level of Risk. I stressed to the guy on the phone that this is more than a high risk...If a car cannot brake properly then its a very high risk to the driver and other road users. I have to ask my dealer to phone them now..(hehe)..and then guy needs to take action very ugently. Ill kepp you lot updated.

 

[jon_r]

cheers boss

 

[McBunny]

i will look see what its like on my 172 as it should be the same id have thought

 

[Dust]

Right....Spoke to my dealer again...now service seem to think that its all to do with lights. Yes lights. If you have 1/2 a ton in the back of your back, the weight will cause the lights to beam higher, blinding other road users. The bar raises the rear of the car when under heavy weight, which causes the lights to sit level...whats the f**king score man??? Are they right or are we?? He said he is almost certain that the Cup is not ment to have this bar???

 

[McBunny]

lol not lights it is there to alter the break bias when the backof the car is lower lol

 

[Cup172(work)]

Load of b****cks about lights, so when I accelrate is there a valve so stop the car front from going up. What is the little switch for which allows you to lower or higher the beam for then!!

Its there to stop the front end and rear end fighting to be the one going foward when you break hard. Anyone been seen an artic. lorry lock its trailer wheels up when empty, its because the bais valve is knackered.

 

[iPap]

Think thats something for Autocar and Which? Would get in touch and make sure that theres a recall!

Its the same sort of thing as on the Valvers, they get messed up if lowered and not adjusted!

 

[Rich-D]

STOP!!!

- - - - - - - - - - - - - - -

Just to let you all know that I have now been and checked with Renault, as well as looking on the ACTIS system and the link is NOT meant to be there on a Cup!!!

Believe me, it aint supossed to be there on a Cup (it is on a 172 though) and I have just seen a Renault tech note with my own eyes that states this...



Dont panic... we were mis-informed and its normal!

No...

Braking split should be 60% front & 40% rear!

When towing a caravan etc the weight would alter your headlight level so you should adjust to compensate. Or so I have thought for many years?

[Dust]

Now i look like a right idiot...ive been shouting at Renault that the Cup should have one...and the servicev guys been certain it shouldnt. lol. ahh well...

 

[jon_r]

change your dealership mate.

I got laughed at for crawling under my car in suit trousers.

 

[Rich-D]

LOL

I was rolling around under tha car with a camera, so I must have looked like a right muppet!



At least we now have a definate answer...

 

[Swervin_Mervin]

Just think about it guys. The hole at the bottom is on a rigid beam which clearly doesnt move (see the rigid pipes coming out of it. At the valve end that is also fixed (see rigid metal hydraulic lines going in to the valve).

Given this, what the fvck would anything do that would be connected between the two, since they are both rigid?

 

[17too cup]

i just read this thread ,i ran out side to have a look at mine and guess what........... it bloody has 1 why ????

im confused guys is it meant to be there or no???

this is quite interesting topic

 

[swelch]

Well my Cup now has it fitted (by Mike172sport) and I tell you it now feels safe when braking and you can feel that the brakes are biased towards the front now. A totaly different car to drive. So unless I am told it has to come out for safety reason it will stay firmly in place thank you very much !

Anyone at donnington can have a look at mine if they like.

 

[D-CUP]

Have you driven non-abs cars before?

 

[chris79]

whats the verdict then ? whos right and whos wrong.
