Cost to replace front discs?

from dragons@gmail.com (jmc) contains these words:


They're not hard to change yourself if you've a socket set. About half
and hour per side, provided there's no unexpected nasties.

How much that'll cost depends on your mechanic. Between £20 and £200 I
should expect.

As for 'em being rusty - where's the rust? If it's on the bits that are
supposed to be shiny it implies that all is not well with the calipers.
Either the slider is jammed, or one piston is seized - depending on the
design of the brakes. This will need correcting as well, or you'll be
wasting your money. Alternatively it's possibly that the pads are
damaged - if one's got a chunk missing for some reason - rare but I've
seen it - then you'll need to replace them as well.

Many people (me included) replace pads as a matter of course if discs
are being changed - though that might depend on how worn the pads are -
if they're almost new then you might choose not to.

I just changed the front discs and pads on my wifes car a couple of days
ago, a first for me, and it was pretty easy.

But there was an odd rust problem on the offside disc, the inside of the
disc had about 2cm rust around the very edge.  It clearly looked as if the
pad hadn't been in contact with the disc at the very outer edge and had led
to the rust build up - but upon checking the pad, the pad had actually been
worn down by this build up of rust.  Most odd.  The discs and pads were
about 4½ years old and pads were only a third to a half worn, car has 36K
miles on it.

Now that you've replaced the bits - keep an eye on it. It's often
sticking slides or pistons that cause that sort of pormbel[1].

Certainly will keep an eye on it.

As to the original question of cost, the dealership wanted £140 to replace
the front discs and pads - which to be honest I think is fairly reasonable
(I have heard of people being charged over £600 for discs and pads all
round - not a Ferarri either, but a Toyota).  But I bought the discs & pads
from Brakes International (www.brakesint.co.uk) for £75 including delivery.
Although I came across a nut on the caliper mounting bracket that wasn't
accessible with a socket so spent a further £4.99 on a spanner!

Hmmm, nothing for a Montego!

Blimey, they don't to antiques ;-)

Oh yes there is.
A complete set of front pads at £10.95 + VAT,
Each front disc is £8.17 + VAT,
Next day delivery for my little lot was £5 + VAT.

Blimey, I should be on commision here :-)

How did you find that? I tried their rather patronising search system
and it didn't list Montegos.

Bloody hiding under Austin/BL, innit!

Guy King (guy.king@zetnet.co.uk) gurgled happily, sounding much like they
were saying :


 

Shock, horror! Austin Montego listed under Austin! The sneaky little sods.

Ah, but mine's a Rover Montego - and don't you forget it. None of this
old hat Austin stuff!

 When asking this sort of question, it's best to give the make and model,
as replacing a disk isn't the same on all vehicles.

Not that it matters, but have you seen the actual MOT refusal form? Discs
all rust when the vehicle is unused, but that rust disappears after a few
applications. They're likely to be either cracked or worn too thin.

Rusty disks?

If your brakes work then brake hard a few times and they'll be shiney again
(well, at least the strip where your pads hit the disks).

If this doesn't happen then your calipers are seized which means no brakes
on that wheel!

Disks vary in cost, but around £50-£150 a pair plus 1-2 (tops) hours labour
to fit. All depends on their size.

Nah they'll never take that long surely?  I remember a couple of years ago,
me and my mate fitted new disks to his Nova :)  We had NO mechanical
knowledge, a shite selection of tools, and only the Haynes BoL for guidance.
Still, we did it in about 2 hours, and it only took that long because it
took us an hour to get one of the wheels off :)

Depends. Some calipers can be bastards to shift, and I had a Renault
Trafic which had the discs so solidly rusted on that I had to belt 'em
with a sledge-hammer to get 'em off.

Been there, tried that and failed miserably

A garage will / should do a pair in < 1 hour easy

But at home you may get problems such as seized bolts (especially the little
screw that holds the disks on when the wheel is removed, and sometimes
calipers need freeing. My old Golf GTi - took about 40 mins for the pair
incldng getting tools out. But once took me 3 hours as I had to drill the
screws out - bummer.

Firstly, a car cannot fail its MOT on rusty discs. The only possible close
failure reason is discs 'excessively pitted', and unless your car has been
parked in the sea for the last couple of years, without being used, then I
cant see that being the case.

What is the exact wording used on the fail sheet, and under what section has
he failed it??



Secondly. you say it is a 'truck'.
Exactly what vehicle is it,. some larger vehicles have the discs fitted to
the insides of the hubs, meaning the hubs have to be removed to take the
discs off, which would obviously increase the time and therefore the price
of the job.


Lastly, if you don't fully trust your mechanic, take it elsewhere.
