1994 RRC Caliper Bolts

Hello
Could someone please advise what type of bolts secure the front callipers? It seems they are either spline or double hex but I'm uncertain. Either way I have no socket that fits so need to purchase one.
Many thanks
Richard

Dealer only.
A standard 13mm 12 hex socket does the job

To hold the calliper to the hub?

I thought they were 7/16? When I needed some they were £8 each from a land rover part supplier so I went to a bolt shop and got a hand full + a box of 3" screws and some pz2 bits for £3 Very Happy

I think i've written the size down somewhere, I will go look...

Mines an '89 though, don't know if that makes a difference?

I'm reading the bolt head from the poster. He's asking if it's a spline head. The later bolt has a 12 hex head and is IIRC 10mm X 1.25 mm pitch.

The earlier Ranger Rover has 7/ 16" bolts to hold the calliper on. Those bolts are available from any good fastener supplier. Believe my you can't buy a 10mm bolt and cut it down. I know, I've tried

Are these what you're after ?

Well, well, well.
Either Island 4x4 are wrong or I'm wrong.
The bolt size is !", yes TWELVE mm x 1.25..
How do I know ? Well you see I double checked with both a spare bolt and the die nut I use for cleaning the threads of those bolts ?

Hmmmmm ????

I see! I checked mine and your right, its a 7/16 UNF.

Do you have to use that head? Couldn't you just use a normal m12 fine bolt?

The one you've linked on island 4x4 is described as 'to bolt disk to hub'? This must be the one you mean't to link?

Good information, thanks Smile

Could you use a socket cap screw or are they too big too? Either way at 50p a bolt it's probably as well to keep standard Smile

I have thought about an Allen bolt. I just nip to the dealer if I need new bolts

Don't talk to me out the back of your head.
You are not even capable of suggesting the correct socket.

NO Land Rover bolt, nut or screw uses a 16mm socket. Think on that.
The calliper bolt head for a 300Tdi Defender , Discovery or a Range Rover is 13 mm 12 hex
I WILL REPEAT THAT AGAIN
13 mm THIRTEEN MILLERMETRE

GET IT.
Now go back to the bolt, nut or screw you are telling me is 16 mm and tell me what is on the head.

You see I haven't been at this job very long. I apprenticed in 1954. &UNDERSTAND NINETEEN FIFTY FOUR. UNDERSTAND
Those days every thing was WHITWORTH. Then I had to learn BSF. Then SAE. Then UNIFIED
NO it's metric.

Incidently using any other bolt to hold the callipers on a 300Tdi will be illegal under the present regulations

NOW DO YOU UNDERSTAND YOU ARE GIVING THE WRONG INFORMATION.

The part number of the calliper bolt is SYP 500090

DO YOU UNDERSTAND

I think you need to take a very good long look at what you say.

Or is it 13mm?

The last person whose brakes I fixed knows but he ended up in hospital, but I do know what he whispered to me............
16mm

Sorry Mmgenemi but I made an initial mistake with 16mm but I do not like being shouted at and could not resist. I would never put someone's life at risk by giving dodgy info about brake parts as after all, this was all about the size of a socket.

14mm
