MR. BEAN STRIKES AGAIN…..

 

Whilst having new discs, pads & braded hoses fitted; I asked my mechanic (not risking this job myself) to whip the callipers off for cleaning & a lick of paint. There is a tiny split on each of the (small) piston dust boots (rears), see pic’s here:

 

Overview: https://www.dropbox....er 001.jpg?dl=0

 

Nearside: https://www.dropbox....er 002.jpg?dl=0

 

Offside: https://www.dropbox....er 003.jpg?dl=0

 

Should I replace the dust boots, if so how & where’s best to secure replacements? I only noted the splits having immersed the calliper after degreasing (boot was full of water & ‘spat me in the eye’ when moving the piston). Doh! I’m tempted to warm some thick grease & syringe it in (displacing water int he boot), sealing splits with a blob of Araldite.

 

Also…. I extended one of the main pistons to full reach, to check on it’s dust boot (by turning the ‘spring’ on the rear). Boots was fine but how do I now get the main piston to retract?

 

Before extending main piston: https://www.dropbox....er 004.jpg?dl=0

 

Piton ‘stuck’ in extended position: https://www.dropbox....er 005.jpg?dl=0

 

Quick responses MUCH appreciated. My mechanic is NOT happy having a lift tied up whist I am fannying about. Thanks in advance. Benzola [font="wingdings;"]J[/font]

 

PS: Still can’t get pic’s to upload, please excuse drop box links.

You have to wind the piston back in with a special tool placed in the two dimples. Long nose pliers can be used but its a bit fiddly. WD40 will chase the water out

Brill. Thanks 5 O'Clock. Generous squirt of Rost Off & piston went back in a jiffy. I'll just be sure my mechanic flushes with some cheap Dot 4, before filling up with my (rather expensive) React Dot 4. What are your thoughts on these here boots? Cheers. Ben.

Thanks very much for that, but I'm not so sure... any second opinions please? And it is a question of just pulling the old boots out & 'poking' new in?.... Here's an anecdote whilst I'm here... Earlier I called The Vauxhallist in Lincoln to see if they had any boots in stock & to get a little guidance... They reckoned that "the entire calliper will need replacing mate, there are no service parts or 'refresh' kits available"... Utter twaddle (I'd already read about 'refresh' kits on here), I couldn't even be ar**ed to correct him... Needless to say The Vauxhallist Lincoln will never work on my car!

I'm not sure that is the right seal kit, they did do one though as I replaced mine when doing a brake/suspension refresh

For others in a jam. Read the Wiki first.

 

Here's the Wiki : http://wiki.seloc.org/a/How_to_Rebuild_a_Brembo_Caliper 

 

Here's the refurb kit: http://elise-shop.co...tml?language=en

Managed to get the callipers looking half decent. Refurbished & painted (pic) here: https://www.dropbox....G_0723.JPG?dl=0

 

For anyone doing same, here is the guide: http://wiki.seloc.or..._Brembo_Caliper & (thanks to Fez, again) hers is the RIGHT (& best priced) refurb kit: http://www.ebay.co.u...=item3f28b8d4c4

 

It was all pretty straight forward (bit of a faff but I'm no hot shot mechanic). I had one little 'glitch'.... the steel component (circled in pic here: https://www.dropbox....G_0709.JPG?dl=0) sits inside this rubber & also sat 'inside' a nylon sleeve when removed... refurb kit contained no new 'nylon sleeves' & old 'sleeves' wouldn't shoehorn into the new rubbers! Reassembled without nylon 'sleeves' but lots of silicone grease... all nice & 'fluid'.

 

Should I be concerned about not refitting nylon sleeves?

Found a schematic: https://www.dropbox....Render.jpg?dl=0

 

Containing all the 'correct' component names (making the - gobbledegook - above obsolete).

 

If anyone's interested, the refurb' kit (kindly linked by Fez) does not included 'Split Plastic Bushes' BECAUSE the 'Lower Guide Boot' has been redesigned making 'Split Plastic Bushes' obsolete (confirmed by both Brembo & Absolute Lotus). 

 

To summarise this tread... Thanks to everyone for their kind help & patience (I am listening & learning).... AND.... Don't s**t yourself (like I did) about doing this job yourself! Take your time, read all of the info & buy kits from links above & you'll be fine! This is NOT a difficult task. If you are calm & careful an hour per calliper, in the shed, no special tools required. 

 

Thanks folks - Ben.
