Fitting 306 Gti 6 Caliper Dust Seals

[cRaig 273 1 Cars]

Hey everyone,

 

I found This Thread regarding the potential difficulty in rebuilding 306 GTi 6 calipers, as Im really struggling to get the damn dust seals on, and then fit the piston through the centre.

Is there an accepted technique/knack I should be using? Already just bloody torn one of the new seals, so rather annoyed about that!

 

Cheers

Anyone offer any tips?

[cRaig 273 1 Cars]

Anyone? Have just ordered another dust seal... dont want to mess this one up!

[SurGie 54]

I need to know as well, iv found no real info on it myself, so iv decided to go to a local brake specialist to sort mine out when i find one.

 

Iv just done a bit of a search and there is no where local to sort mine out. I was told by one firm to go to a local garage that does that sort of thing and they will sort it for me for £20 for both calipers.

 

INFO for other's > At brakes international they sell the gti6 caliper dust seal kit for around £15 each side, the part number is > BCK 5719

Have a look at my project thread in my sig (page 2 I think ). There is some pics from when I did mine. Its not a hard job to get them in. I used genuine seals as I have found in the past, some cheaper ones dont fit right and are not the same quality. Iirc I fitted the main seal, then the dust seal, then fitted the piston and slid it in until the dust seal popped into place.

 

Hope thats of some help Craig

Thanks for the reply

 

I got the rebuild kit from Big Red, so quality shouldnt be the issue. I think with the dust seal fitted prior to putting the piston in, I guess the knack is carefully stretching the seal around the piston, without just forcing it in.

 

Will try again and see how it goes

Which ones did you use that were not as good as OE ?

 

I would assume a total brake parts supplier (not many of them around) would be just as good as OE, where did Peugeot get them from originally, i doubt they would make them themselves with Pug cost saving as usual.

[cRaig 273 1 Cars]

The calipers I am rebuilding originally came with lucas branded seals, so I would guess that was the OE supplier from pug

[SurGie 54]

I should have realised that, doh

 

How much did the Big Red one's set you back ?

[cRaig 273 1 Cars]

Heh, I guess on second thoughts it is fairly obvious The bigred kit was about 24 quid I think for both sides.

Anyone got any more advice for this job? Ive just managed to split yet another bloody dust seal. They are quite expensive buying them seperately!!

 

How do people stretch the dust seal to fit around the piston once it is fitted? Access is a nightmare, and I cant stretch the seal evenly to fit the piston.

 

And this rate I might just go back to 1.9 calipers, alot more straightforward!

are they the correct diameter? been some time singe I took front ones apart but the rears I did a few weeks ago were very easy seal wise, just the mechanism a right faff to get back together!

[cRaig 273 1 Cars]

They seem to compare to the oriiginal lucas seals. I tried fitting an old seal just to see if I was going mad, and I was struggling with that one as well.

 

I just cant see how it is possible to fit the dust seal first, and then squeeze the piston through it, as the seal is considerably smaller than the piston!

 

Noone else seems to struggle with it, looking on the 306 forum etc. maybe Im going mad..

[welshpug 1,657]

now you say it...

 

 

 

[marksorrento205 80]

Have you spunked it up with some lube to help it along?

[cRaig 273 1 Cars]

Yep, lots of red rubber grease used

I've just rebult the lucas calipers on my 306 hdi.

 

I used a bigg red kit & just wiped the bits with new brake fluid to assist getting the to slide together.

 

I also fitted the dust seal onto the piston before locating it into the body.

I saw a nice trick on the bmw S14 forum last night, use a little compressed air to get the seal up over the piston

Looks like a nice trick!

I know this is a really old thread but having rebuilt a few sets of these now and remembered each time the main dust seal is a pain to fit, and trying to see how others get around it.

 

Couple of people asking how to do it as they kept splitting the seals trying to do it the normal way, and the fact is the seal is too hard to grip and pull up whilst trying to manoeuvre it over the piston.

 

I find to do it the following way will save you a lot of hassle, and it's to lay the piston on it's side so that it isn't naturally pressing through the dust seal as you do it. 

 

You'll find it a bit easier to coat the bore of the caliper and the piston in brake fluid to help it slide around.

 

Step 1 - fit the seal like the below

 

 

Step 2 - slot piston and seal into the dust seal groove

 

 

 

Step 3 - Turn caliper upwards and gently ease piston into the caliper. You will feel it grip the dust boot and it will naturally hold it in place.

 

 

Step 4 - grab the edge of the dust boot with a seal pick etc being careful not to rip it, and pop it into the groove

 

 

Step 5 - I found it easier to rotate the piston around in circles to get the seal in place on all sides

 

 

Job jobbed

 

Some people get lucky and fit them perfectly without issue, but sometimes aftermarket seals vary slightly and are a proper pain to apply. I found the above turns a 30 minute hassle of fighting the seal and trying to pull it around the piston whilst it's upright, into a 10 second job.
