Okay, another problem has arisen with my car... Earlier u was driving down the road, when all of a sudden I heard a clonk in the rear right hand corner. Now ever since then I am now experiencing a lot of vibration when braking and every now and then It will make another knocking noise until it's settled.
My bet is that it's the brake caliper that has come lose or a brake pad that has dropped out of place. But i can't be for sure. I have checked the wheel nuts and they are all tight, and now I'm stuck in my car, in a m6 service station because it's pouring it down.
Cheers, Mo
-
Found the problem - the whole caliper and carrier is hanging off... Just my luck... Any temp fixes anyone can think of?
- both carrier bolts are missing
-
Why would you want to 'temp fix' a brake? :shocked:
Go to vw or if you cant afford a few quid for some bolts, go to the scrappy.
-
Like I said, I'm stuck in a service station on the m6... I have no other choice than to temp. Fix it or get recovered, and I don't have any breakdown cover... :cry:
-
How on earth have they come out??!
The only fix is to replace the bolts, don't drive it until then.
-
No bloody idea how they came out... I have been driving it around for well over a month, since the back brakes were changed, so it isn't an immediate thing that caused the to work their way out
-
You still got the bolts at all if so I would put them in n try tighten them up best you can but we'll risky trying to temp fix brakes unless you can take the whole calliper off and drive with 3 callipers but be extra carful
-
Bolts have dropped out somewhere, so I no longer have them, something I thought of doing, is to take the pads out then cable tie the carrier / caliper back on. But then I'll be using 3 brakes only and 3 brakes when it's raining is a recipe for disaster.
-
Pay to get recovered or failing that call someone to come and pick you up to get done bolts to fix it at the service station.
A temp fix is a disaster waiting to happen.

That's a recipe for ending up in a ditch, the rear brakes don't do a huge amount but if you've only got one side working and have to slam on the car will be all over the place.
I really can't believe you're contemplating it :shocked:
-
If you take the pads out you'll pop the piston the first time you press the brakes leaving you in a worse situation. Have you got any molegrips in the car? You could put them on the flexi to render the caliper inoperable then limp it home. Or get a mate to bring you some bolts..
-
I was thinking to crimp the pipes and remove the calliper all together but it Is so risky but dom is right they don't do a lot but like people say just get a mate to bring some bolts up or pay to get toed home good luck mate
-
Out of the many ways you might have a big disaster by driving this car home, I think the loose caliper getting jammed between the wheel and disk/suspension is most likely. This will lock the rear wheel and probably cause a spin out.
If you luck is really bad the wheel will break up and possibly cause a roll over.
If you don't have £100 for AA membership (and yes, they will recover you straight away) then call your Mum, best mate, partner whatever and get a loan from them.

Cheers for all the replies, and yeah, a bodge job was out of the question really. I've managed to use a family members breakdown service, so hopefully they'll fix it on the spot, and failing that, I'll have one hell of a journey back home to Essex...

Is the right answer. Well done and thanks from me actually.
If they fix it on the spot I would like to know how. Having the right spec bolts in the right size in the back of the van..?
I reckon it will be the long journey so get him to stop off on the way for a bottle of wine or a pack of beer (or whatever) for when you get home...
-
Haha, will do, and I told them over the phone what I need to fix the car, as it is only a 10 minute fix, so it would save them a lot of time and money to just to fix it on the spot. Only time can tell now.

LOL.

Oh dear haha, Does anyone know what size bolt it is that I'll be needing btw? It connects the carrier to the frame of the brake
-
M10 bolt, 1.25 pitch, 30mm thread length

LOL.

Like it :tongue:

they should be tightened to 65mn too

I've finally got myself home, after a long drive back. The guy had some spare bolts in his van that half fitted, so he put them through, then put a nut on the end of it as extra safety. Not ideal I know, but it's got me home, and I'm now in the process of ordering the new bolts and LOCTITE.
Also, according to the rac guy, towing back was out of question as it was too far. And i didn't want to pay to stay in a hotel over night.
Cheers for all the help and suggestions. I'll be sure to pack the bolts with loctite when I refit the new bolts
-
M10 bolt, 1.25 pitch, 30mm thread length
I've just given a bolt place a call, and they are after the complete length of the bolt - including the unthreaded area of the bolt.
So would is it 30mm total length still or is it something like 10 mm unthreaded, 20mm threaded?
Cheers, Mo

The trouble with bodging brakes is they may well be fine under light braking but things give when under pressure i.e hard braking.
Normally that is when you need the brakes the most!
Just go VW or TPS they are a matter of a couple quid tops.
-
I asked VW and they said that they don't sell them individually, they only sell it with the carrier itself, and that costs loads to buy.
And yeah i know, the temp fix has got me home, but i'm not intending on driving my car anywhere whilst it has only got this temp fix. Luckily there was little to no traffic on the way back home last night, so i ended up having an almost straight run (200+ miles) without having to use my brakes anyway.
-
Vagcat suggests the following. Give a dealer the part no and surely they'll get them for you - I bought new front ones late last year. Vw / Seat / Skoda / Audi will all be able to supply them.
N 90729401
allen key head bolt
M10X1,25X21 /
Edit; They are fully threaded bolts iirc and if you buy them from a bolt place make sure they are the correct tensile strength..
-
They are fully threaded? When I had them off a month or so back, in sure they were half unthreaded? Or doesn't it matter?
-
Whip one off the other side and measure from the end to the sealing face of the head...
Make sure the bolt place gives you at 10.8 spec. (This specifies high tensile bolts).
You would be better off getting them from VW if you can though. A lot of the critical bolts on my Mk3 and Mk4 have some sort of green coating. I assume this is anti-rust but it doesn't look at all like zinc to me.
-
I might give it a go a bit later as I'm going to loctite the s*hit out of the other side now , and vw don't sell them Individually, so I'm going to have to coat it with an anti rust agent too probably, unless they come like that normally
-
I have never seen "proper" caliper bolts go rusty. I would only be worried with the ones you would get from the bolts place as they will be general purpose and not specifically designed to live outdoors.
Have you got a scrappy near you? That is another option.
If you are stuck with general bolts, get 10.8 ones and give the heads a light coat of grease. They should be fine.
Also, make sure you get Loctite thread lock and not retainer. Thread lock (usually blue) is made for disassembly. Retainer (clear green and it stinks) is basically strong glue.
-
I have the thread locking stuff and there aren't any mk4s nearby in the scrap yards

You are right there.
I live a few miles from Silverlake which is a huge breaker. They (I am guessing) have 300 cars being broken. Plenty of Fords, acres of Vauxhalls and French cars. A half dozen each Passats and Polos. Probably 10 Mk3s. And 1 Mk4. I was very surprised.
-
Thats because Mk4's don't belong in a scrappy!
and I've had all my bolts off on the other side now to make sure they weren't loose too, and the other carrier bolt didn't take much to crack off, so i've now loctite'd all the bolts (a novice fitting mistake i know!) and i'm just going to buy the remaining bolts tomorrow, then i should be on my way :smiley:
Also the knocking noise i heard the other day that i posted about seems to have stopped :grin: so it looks like i had plenty of warning before failure :rolleyes: though, it did sound like it was coming from the rear - passenger side corner, not the drivers side.
Also i thought i should add - i was wrong about what the bolt looked like too haha (excuse the ruler that looks like it belongs to a 5 year old, it was the only one i could find)

TPS sell them seperaty.
-
rubbish they don't sell them seperately, bought some recently from the dealers
30mm thread length from that pic then like I said :wink:
-
According to my local dealers they only sell them with the carriers, I ended up going to a specialty bolt place in the end, which probably saved me an arm and a leg anyway :smiley:
It's all fitted now too, so I should no longer have to fear my back brake falling off again :grin:
-
I meant the dealers are lying not you :wink:
-
Ha I realise that, unless the dealers are different by location, in which case he may be telling the truth
