As I had my 250 off the road for a few days I thought I would smarten up my calipers a bit. This is how they looked before:- I cleaned back to bare metal with wire brushes. They were then painted with an acid etch primer Followed the next day by two coats of foliatec caliper paint (sprayed NOT brushed). After allowing to dry for 24hrs, I fitted the "Brembo" logos and sealed them in with a couple of coats of VHT clear engine enamel (after first checking compatibility with the foliatec paint). Fitted a new set of seals and dust covers obtained from Bigg Red and reassembled. Finally, fitted back on the car with a new set of braided hoses.
Here's what they look like fitted. Is there a way to get the photos to show in the post rather than having to click on the link?
Yes I'll do the rear calipers next time I don't need the car for a few days. What we need is a communal set of calipers so we can rebuild them, change them over, and pass the old ones to the next person that needs them
I'm afraid so, you can't really do any dismantling of the braking system without the need for bleeding . I used the opportunity to change the fluid through the whole system
Nice one Stu! Really want to do mine some time soon, but my Meg is my daily driver so maybe i think i buy a spare set of calipers and refurb them
Did you start at the back and work your way forward? Also how much fluid did u need? This is my first time doing the brakes and I've read some conflicting stories
Yes Same here, but those big brembos don't come cheap (especially for the 250) So I had to bite the bullet and do without my beloved for a week
Hi Torch, when bleeding the brakes it is normal to start at the caliper furthest from the brake fluid reservoir and work your way closer. I would highly recommend you buy a "Gunsons Easy Bleed" (around £15 on e-bay) and follow the instructions with it, couldn't be easier. This is a pressure type brake bleeder, I would avoid vacuum types . If you are changing the brake fluid completely, you will need a litre of fluid, if just bleeding the calipers, half that should do it. P.S. You may also consider having something to hand to clamp the rubber brake hoses. This will stop all your fluid running all over your garage floor overnight. (e-bay search, brake hose clamps)
Cheers mate I'm starting to get a better idea of how it's done i bought the vizibleed kit which is the old vacuum system but that should do the job? ive also figured out how to cycle the actuators in case I get any air into the abs pump. Fingers crossed I can get the pedal feel just right
Thanks for that, you shouldn't really have any problems with the ABS. But strictly speaking, if you are doing a fluid change you should cycle them to flush the old fluid from the abs system. Didn't even think about that when I did mine
Yeah, I had a bit of a problem too, got it sorted by giving them the brembo part number off one of the dust seals. This identified the diameter of the pistons, job done
