It is ONLY for the Bob Brown hub conversion and PNM setup and will not fit a standard Elan.

The discs are £19.95 + VAT each.
It's recommended to change the pads too (arounds £15) although the original PNM profiled pads do fit but have a smaller pad area on the larger disc.



Does anyone know a part number cross reference for these 256mm x 11mm discs? (as I am trying to source them locally rather than have to wait and pay postage) - plus I need to exchange the 236mm ones ordered in error.

The ones I was sent are Bendix branded - though there doesn't seem to be any sort of part number on the box.

Part numbers for anyone else interested in the 256mm discs (11mm thick). These are from an Astra G (mk4) 1.2 16v (not sold in the UK). Euro Car Parts don't stock them as they haven't sold any in years(!) but they appear to be readily available on eBay.

We'll I wouldn't proclaim to be an expert on the matter - but since they went to the effort of having Bendix printed on the box, I thought that was a reasonably reliable indicator :roll:

In fact searching eBay for some of the numbers on ab2cv's list actually brings up the very same box www.ebay.co.uk/itm/Vauxhall-Astra-1-2i-1-4i-Pair-of-Front-Brake-Discs-Solid-Bendix-562068B-/122031768932?hash=item1c69a90564:g:o50AAOSwd0BVwkBm

Which happily also has a cross reference table - could be very useful!

Re: PNM engineering rear brake calipers

Postby ab2cv » Sat 04.03.2017, 14:32

OK so I have a new problem with my PNM calliper kit. When I bought the kit, I told Peter that I had the Jeemy/BB hub kit fitted. They said this made a difference to their kit.

Now due to issues with the hubs, I am trying to temporarily revert back to using standard discs. However, when I install the standard discs with the PNM kit, the outer face of the disc fouls on the carrier. So whatever PNM did to adjust their kit to work with the Jeemy hubs now means it doesn't work with standard discs.

Question is, what is my best option to resolve?
1. Get the outer face of the standard discs skimmed (by 1mm?)
2. Contact PNM and see if they have a different caliper carrier (or whichever bit it is) they can supply to work with standard disc setup
3. Add some sort of spacer/washer to the caliper carrier to step it out by 1mm
4. Buy a normal car before I forget how to drive

Grateful for any advice

Option 3 - spacer/washer. Got spacers on my HiSpec rear caliper to move them further out to run 264mm diameter discs in 17" wheels.

Thanks. :-)

Have ended up using 1mm washers to space things out - this resolved things on one side but it was then hitting the other face on the other side - so I ended up getting both discs skimmed as well.

Now lining up perfectly but my next challenge is winding back the caliper piston. Is this (easily) possible without buying the proper tool from Halfords? Clockwise direction with a bit of downward force?

You should be able to wind back the piston with a pair of pointy pliers and some perseverance.

It takes seconds with the correct tool which I have if you need to borrow it. :D

Brilliant - thanks - I'll see if I can persevere then - can get it to turn but not go in - tricky turning it and applying downwards force - but at least I know it should be possible!

Hmm about 18 months ago I posted on here about a leak I had from one of the mk4 golf calipers which Peter replaced focus well took the car out last night and had the low fluid light pop up. Pulled over and it was low on fluid so popped to the garage and topped it up to get me home, was too dark to see anything but I'm betting it's a caliper again :? Hope not but will have a look when I get a moment and some daylight. Suggest that anyone with the same calipers keep an eye on them though.

I just phoned PNM today because I found a small puddle of brake fluid on the garage floor under the rear right tyre. I removed the wheel and found the inner brake pad and inside face of the disc covered in gunk and brake fluid. It looks like a seal has gone.

PNM asked me to send the caliper to them for rebuilding and for them to investigate what has caused the problem. Not sure when I’ll be able to get it done - probably after Christmas.

I fitted the new 15” wheel rear caliper set in March 2015, and first noticed a drop in brake fluid in June this year.

I’ll report back once things are sorted, but it won’t be this year!

John mine went on in 2013 and one was faulty on delivery and the replacement failed March 2016. The replacement for that is the original failed one that was rebuilt so I will have a look when I get a moment and also report back

Jamie hope you are sitting comfortably :lol:

The fish is called Rambo :D and was part of a 9 fish catch over 4 nights at the end of August. They were between 27-41lb and Rambo was 41lb so a Pb for me. Lake is owned by a friend and I will be going back at the end of April for a full week and hopefully again start of June for 10 days. I'm a noddy compared to my mates but that session saw 12 fish between 5 of us so there has been a little bragging and banter :lol:.

I did have a stunning common at 39lb which is my common pb and much better looking but Rambo is one of the top 5 to have hence using the picture. He gets his name because of a lump on his face apparently.

41lb :shock: , Absolutely awesome, I bet it took a while before that came to the net!, what bait did you catch it on?. Sounds like a lovely lake indeed. I wont tell you my PB on Carp but it aint a fraction of that one :D (mainly a Salmon / Sea Trout fisher), although there were a good few large specimens in a pond very close to me but the Poles came and emptied it.

Very well done, and tight lines for 2018. :wink:

Surprisingly not a lot longer than a 20lber. Balanced tiger nuts are the bait of choice and I'm just as happy catching anything. I am very envious of your salmon / sea trout catches you have and a 1lb trout is my biggest. The European issue gets some heated talk from my friend and I reported some guys on the Thames near Reading this summer wandering around looking for pike and living in a tent.
