Brake Caliper part number confirmation

[lawsy]

Hi all

I've been doing lots of looking around and cant find the answer - sorry

So I've foudna website witha good price on calipers except they have several applications listed, the one that looks right is OE part number 4773035080

is this correct for the LN130 (or will it fit)

thanks in advance

EPC says 47730-35090 Right Hand and 47750-35090 Left Hand.

Want to share the website location?

there are loads listed on http://www.mitsubishicarpartsuk.co.uk/

for some reason

its hard to work out which is which as they dont list any diesels and list loads for the surf/4runner in all different sizes

these 2 however

http://www.mitsubishicarpartsuk.co.u...duct_info.html

and

http://www.mitsubishicarpartsuk.co.u...duct_info.html

have the 4773035080 OE number against them

then doing a search on 4773035080 brings up images of calipers that look identical to the ones removed from mine, piston size etc is the same
I was tempted to order them at those prices and take a gamble (if not i know they fit early 90's pick ups so could sell them on)

but is there really loads of differences between them all? I cant see toyota having a slightly different calliper for each and every model

using the number you gave me nev, they are £81.33 on their website - almost £50 dearer

I wonder what the differences are..

I think you will find (the EPC seems to confirm this) that the number you have is for the earlier model Surfs with smaller discs. They will however fit later Hilux.

But not the facelift surfs then

that explains that then

thanks for helping confirm this Nev..

Early callipers have 42mm pistons, latter 45mm.

oooh 3mm difference, cant make too much difference..

I'm assuming the calipers would be a different size too tho

however putting in the part number you gave into their site it says 54.4mm

confused.com now

my pistons with a tape across them looked about 43mm

The Caliper, rotors and pads are matched to each part so changing one requires changing the lot. Having said that the earlier pads will fit the latter but will be slightly (about 1mm) outside of the disc edge. Don't know where they get the 54.4mm from.

Here's some info on brakes that we have on the Aussie site.

Their site may in fact mean 45mm pistons X 4 for each caliper.

3mm over the area of a circle is:

A = Pi x R2

3.14 x (42x42) = 5,538.96 then find the square root:
74.4mm is the area with 42mm Pistons

3.14 x (45x45) = 6,358.5 then find the square root:
79.7mm is the area with 45mm Pistons

thats a difference of 5.3mm - no idea how much difference that makes in the real world though!

basically i was trying to find out if the £36 calipers fit instead of the £85 ones.. lol

if the external dimensions of the caliper itself are the same and bolt up to the bolt holes then will ti really make much difference.. I guess there would only be one real way to find out


Nev - pad sizes make sense, my old pads overlapped slightly..

[NiftyNev]

13.854423602331 cm2 surface area for 42mm pistons and 15.904312808798 cm2 for the 45mm pistons.

I think they will bolt on but I dont't think the earlier calipers will fit over the latter rotors. Early rotors are IIRC are 20mm and the latter 25mm.
