Fit or I'll make you fit. Bimbos

[VeXeR]

Bought these from the US in somewhat poor condition, so they were cheap;



4 pot front Brembos from a Posrsche 996/997

New seals, pads retainers etc;



Have to love how easy they are to deal with. No rusty pistons like half of the calipers I have to rebuild for people.




New seals





Couldn't be bothered making up caliper adapters, so bought the ones off Ebay to fit the Corsa Burg;



They take M14 bolts, so had to bore the Porsche calipers from M12 to M14 using a reamer.

Didn't want to go up to a 345mm disc, mainly due to increase in unsprung weight by using a larger disc, so had to make a few measurements to keep the 321mm disc.

Bought Pagid RS15 (Grey) pads in from Germany. Expensive, but Pagid's best;



Calculated by aligning everything that -12mm was required from the caliper/carrier.
10mm from the caliper and 2mm from the carrier decided upon.

Off to visit an engineer who owes me a few favours;







Shaved off those necessary millimeters

More test fitting;



No need for spacers, yet extremely tight, barely room for paint;



Speaking of paint, lets keep it standard looking;



Brembos stickers to replace the Porsche stickers.
High temp lacquer;



Adding lightness;





All in, half the weight of the originals

Had to swap over the bleeders to the opposite side. Air being less dense than brake fluid meaning it'll float to the top, so needs to be bled at the top;



Some Castrol React performance dot 4 mixed with some tech;



If you're going to spend over €200 on pads;



Sprayed matt black with VHT 650 paint;



Probably overdid the piston lubrication on the pads when I rebuilt the original caliper. Serious wear on the inner side;



Not to say that I didn't lube the slide pins also.
I'm heavy on brakes when I do use them.



Alignment needed. Think the carrier needed an extra 3.8mm or so shift inwards. Made up spacers and bought in 12.9 grade M12 x 40mm carrier mounting bolts.



Also, brake lines; awkward one. Bought BMW E36 Hel braided lines to Porsche calipers, same M12 X1.0mm female end as the Opel/Vaux. M10 X1.0mm make 90 degree end to plug into the caliper.





Gave the wheels a wash. I drive about 100miles round trip to/from work



Out for a spin to knock off paint;




And that's the simplified version. Doubt ye want to hear the complicated version.

Advantages;

Reduced unsprung weight- essential with some of the uneven roads I drive daily.
Better braking power.
Looks better under the wheel.
Far more choice of brake pads.
Cheaper 321mm (standard) brake discs.
Somewhat unique.
More even pad wear.

Nice to see you get upto other things than drinking that sauce ........

More quare stuff in the pipeline....... including Irish cream liquor.

How cheap is "cheap" btw? Are we talking the cost of a lamborghini to Richard Branson cheap or .... The cost of bed and breakfast to a tramp cheap? .....

[VeXeR]

Under $200 inc. postage

[w20adm]

That's barmy. ..... you must've done a few "favours" ....

[VeXeR]

Damn good refurb needed. Missing spring retainers, pad retainer bar, cotter pins, all seals completely shredded.
The aluminium mono-block mass makes for cheap postage and I got all the seals and refurb bits cheap also as you can imagine.

Blew quite a bit on pads, discs weren't cheap, caliper carriers a necessary evil to save on time.

I'm always owed a few favours as I'm a giver :P

I'll bet you are ......

Furthest I go with brake upgrades is new fluid once in a while.

Last car I had, brakes had some unique pieces built.
Larger brake master cylinder. Nice high biting point and proper man-pedal with the resistance in the pedal.
Brake master cylinder stopper which mounted to the chassis leg for strength and rigidity. The Opel's brakes still lack feel by comparison.
And all the usual brake upgrades inc. braided lines.

It's always good to change her fluids, though I hear she resisted you last time!
