Iq Brakes

[Phatjellybelly]

Well I have had some old bangers in my time but I have never had to change a pair of disks because they were rotten and on a 3 year old car? 5 year warranty, forget it brakes is wear and tear innit, unsuitable materials don't count even though there is a serviice bulletin regarding rusty discs. Very dissapointed in you Mr T.

[FROSTYBALLS]

You've done better than my neighbour's son with his 2011 VW Polo (bought new) - front discs replaced as goodwill by VW due to overheating/warping at first service (11,000 miles). Second pair replaced for same reason at second service (22,000 miles) at his cost (£250). Third service coming up (33,000 miles) - front discs need replacing again. First issue they've had with brakes with the cars they've owned. VW swear there is nothing wrong with the car.

Common now with a few manufacturers, Skoda, VW, Audi, Seat really quite bad these days.

Particularly bad these days are Subaru, just look at cars sitting on forecourts,

calipers and discs very rusty.

(Just cosmetic sir!)

Some of my pics.

Going from the top.

These rears on mine with the Red Calipers are at 8 months old.

The Hub and Wheel centre is how they go because the Hub gets no grease.

The Drums on a Fabia are how the are after 2 months.

They put them out unpainted, as shown.

The Front with the Red Calipers are on a new demonstrator car with 35 miles on it.

That has been sitting about and getting washed daily.

By the time it is sold at 3,000 miles those will be needing Skimmed or replaced.

Bottom right, new unregistered in the showroom.

My four discs (TOYOTA iQ 1.0) are okay after 15 months, 10,000 km and a strong winter with a lot of salt on our roads. Could you tell us more about the mileage of your iQ and the way you use the car, in particular whether there were longer breakes? Thx.

The most common cause of brake disc warping (Post 2,) is people holding the brakes on once they have stopped. Brakes will create a lot of heat if used in anger and the big cast brake disc can dissipate that heat quite quickly but the smaller brake pads can't. If you pull up in a hurry at a set of traffic lights then sit there with the brakes applied you locally heat that area of the disc while the rest cools.

I suggest it's a problem with your neighbours driving rather than a VW problem, The handbrake is there for a reason but people never seem to use it these days especially on automatic cars.

Brake discs will rust, they are made of a material that rusts and you will never stop it. Looking at the pictures on the first post the pads should have been changed long before they got to that stage, Was the car ever serviced? Are they front or rear brakes?

Craig.

[FROSTYBALLS]

Yes I know about the issue of warped discs through holding the car using the footbrake - and mentioned this to my neighbours son when they had the first set of discs replaced. They use the handbrake.

They never had issues with their previous Fiestas.

Not only do the discs on the Polo warp, but they also become blued due to over heating and the blueing isn't localised.

Craig,

Why would changing 40% worn pads stop my discs ending up like this? they have not been gouged by pads worn down to the metal they have RUSTED like this. Yes the car was serviced less than 4000 miles ago by the dealer I bought it from as an approved used Toyota, it was serviced when I bought it last October at 15,000 miles and I had it serviced in April at 25175 miles and visual safety report/estimate stated rear pads 30% worn, disks pitting although they were not as bad as this then.

Not all disks rust it depends on the material they are made from but to have disks rust to this extent in 3 years is unaceptable, I had a Ford escort for 14 years 108,000 miles which went to the breakers with its original unrusted disks, I had a Ford Puma changed the disks after 9 years 68,000 miles through wear not rust pitted friction area. If this is not a Toyota issue why is there a Toyota service bulletin showing 6 pictures of rusty disks and which oned should be changed?

Think I have answered your questions except the car is in regular use probably 6 days out of seven.

Re the 14 year old Escort and 9 year old Puma,

many of us will have had cars from the 60's, 70's. 80's etc with Discs that did not rust.

Rear Drums (exterior) or Discs that did not rust.

But thats then and this is now, different materials. different Brake Pad material.

Different era.

Some rust badly and some not very much.

I had a Hyundai that had badly corroded discs after one winter from new, & i have a Kia thats is 7 years old and only does a few hundred miles a year and the discs have had a little surface rust and i skimmed them.

I have a 9 year old Suzuki that got new discs at 9 years old.

Brake surface was perfect, edge was just too nasty looking,

Some iQ's Discs get more corrosion than others do, its just how it is these days.

Buying a Mercedes or BMW will not guarantee non corroding discs.

Cars get fancier, more electrics, Euro 5 emissions, soon to be Euro 6,

Lighter cars, bodies with 12 years perforation Warranties etc.

But,

Nobody builds a car to last for ever, or they would never need to build cars by now.

Not even Lexus.

They need to penny pinch and also to keep building cars with limited life spans.

Replacing discs is hardly an expensive matter,

just annoying.

(discs can be skimmed though.)

Many Car Washing products are responsible for the state of Corrosion on vehicles these days.

People worry about 'Wheel Cleaner' that will not spoil there alloy wheels, but it is amazing how many products effect the discs and other parts.

& Other environmental factors more than just road salt.

I was gutted when my 28 year old 130,000 mile Mercedes 123 needed its discs replacing for the first time, I decided to replace the discs calipers and pads. Pads were £10, Discs £35 a pair and Calipers, genuine, were £45 each. How much are they on an IQ with "running in" mileage on?

[s44gtw]

From a Motor Factors £52 a pair for rears & £49 a pair for fronts, rising to around £80 a pair from fancy places.

All different qualities available, some even cheaper ones may be better than OEM from Toyota.

Hi Scimberk,

Yes its atrocious isn't it only 28 years and 130,000 miles hardly quality kit is it

I don't know how much Mr T's offerings are as I sidestepped them based on the durability of the originals and fitted some Mintex ones which I have used before on other cars which cost me £55.00 for a pair of disks and pads, labour was my own so no cost there.

Best

[s44gtw]

Bargain for discs and pads for £55, well found.

george

[scimberk]

It is awful quality isnt it Dont now why I used that icon, I just liked it.

£55 isnt bad for a modern car, I just wonder if fuel economy isnt offset by parts cost and replacement, still, cars arent a cheap hobby and I have found that since I got the current IQ, Ive never been out of it. I even missed the sunshine in my convertibles to play with it.

Thats a weird one as well

[bobkneale]

I expect and have experienced on many of my previous cars, over 100,000 miles without the need for any brake disk replacement.

I have come to the conclusion that many modern cars parts are designed not to last as long.

The answer perhaps is to buy and good old Merc and completly rebuild it to better than new standard then keep it for 450,000 Miles or about 25 years !

[tarquin]

My Peugeot 406 257,000 miles same discs wafer thin though lol seriously though was a pukka car.. Only passed it on because i got the iQ

The technical service bulletin is not headed faulty brake discs on an IQ is it ? It is a warranty support bulletin reminding dealers who may not be applying proper diagnostic processes how Toyota expect brake corrosion claims to be handled the photos are there as examples showing what Toyota do and do not consider to be warranty issues and is applied to all models. If your car is under warranty an exhibiting one of the issues Toyota do say is a warranty fault get onto your dealer, other wise pay to replace your brakes as you see fit.

[sweet-dentist]

Of our cars (Toyota Verso / Smart / iQ), all of them show brake-discs that can rust when it has rained. Looks like there has been water on the discs splatterd.

But it did notice to me that the discs of the iQ were faster with rust.

After some days standing next to our house, this would give a scratching/sanding/grinding noise when I would drive of the side of the house to the street....when stepping gently on the brakes.

Until now I do not think much of it and I am not concerned. But will keep a good eye on these discs to see if something is getting worse.

BTW.... .. Yesterday I went to the Toyota garage cause of the older model EGR in my iQ from 2010. The car shows sometime some slower accelleration at a trafficlight. They looked it up and found the problems with the EGR in there Toyota database. I have an appointment next week. I will keep you all informed what happens.

In Holland we do not have an iQ club anymore so I do not know what is going on with the other iQ's. Thought that this problem was more in England... Or they handled the problem better in England.

Enayways .. He recognised the problem and said that this is all a warrenty thing. And I have an extended warrenty till 2015. I bought 2 years extra....when I bought the car it was standard 3 years.

[Alan4908]

Help please! Is there a service manual for the IQ2 ? There seems to be a complete dearth of info out there on the car! I can't find any reliable dwawings pr procedures for replacing /servicing rear disk brakes on the car.

Any and all help will be much appreciated

alan

[FROSTYBALLS]

Nothing like a Haynes manual. You can access service information from - http://www.toyota-tech.eu

Be aware that some info is free and some is chargeable

[iQofaMouse]

With regard to George's comment on cleaning materials; my discs turned beautifully black yesterday after using an iron out decontaminator on the alloys (must be the acid content) as well as on the paintwork. It soon cleared after a long drive but it makes me wonder if there could be any lasting damage though...

Nicola

[iQofaMouse]

George's MUCH earlier comment it seems... Not navigated the club page on mobile before and it seems as though I should stick to desktop! Sorry all.
