In process of fitting UK brakes....

No mate - no screws, "supposedly" just sit on the hub.

 

Matt H posted a while ago:

 

"remove the old caliper and the disk should virtually fall off, (may need a little persuasion but mine didn't)"

 

Its had more than a little persuasion and its not budged :(

 

EDIT: So is it just a case of when the caliper is off the disk should come off? Or is it fixed in some other way - its not budging at all and we've plusgas'd it and been banging it with a 4lb claw hammer all afternoon.

 

I can't believe I've really achieved nothing all day, its sooooo frustrating.

 

The prob with the SS hoses looks like the pipe on the car was overtightened originally and its flared out so won't fit in the SS hose properly. Looks like a fair bit of careful filing involved tomorrow to get it on.

There aren't screws holding the disc on, there are simply one or two bolt-holes (M6 sized I think) where you put a spare bolt in and tighten it up. The bolt goes through the hole and pushes against the hub, thus levering the disk off if it's rusted onto the hub. Strangely more effective than twatting it with a hammer because the force is where it's needed.

I've always used releasing fluid (penetrates rust), that combined with a hefty clout from a club hammer against a block of wood behind the disk has always done the job. If I were you I'd give Chris Wilson a quick call tomorrow and see what he suggests...

'Getting very wound up, always try these things and end up wishing I'd just paid a mechanic to do it.

Glad you picked something easy to start on !!!!!!!, the brake pipe ends allways seem to be a bit too flared (like Paul E's trousers) to go in the ss hoses , bleeding it can be fun too , BTW i charge £150 to do this :sly:

In that case I'm glad I'm doing it!!! LOL! ;)

 

I like to think I'm not a mechanical numpty but things just weren't going today! LOL! I've done disks/pads on numerous cars before, exhausts, clutches, gearboxes etc so I thought that brakes would be similar or easier than a clutch!!

I guess its not too hard a job, just can become it where there are little bits you don't know! I'm determined to crack the buggers anyway ;) (not literally!!!) :D

 

As for the pipes being flared - how do you attack that dude? Carefully with a file too ont he very end part until they pop in ok?

And a good flush with brake cleaner to get rid of any particles.

 

I used a 2 lb hammer. If you are not using the discs again, forget the wood as it absorbs too much of the impact.

 

Are you sure there are no bolt holes on the JDM discs there are on the UK's.

 

Could this be the one advantage of owning a UK car? :devil:

J-Spec brakes have 'puller' holes

TBH Neil, if you're not 100% sure what you are doing, get hold of someone who does.

Dude:flame Dev

 

Cheers Dude :D Gonna get hold of a fine file and plan was to do them finger first already :D (and aye, I have a brake pipe spanner :D)

 

Ta :)

Cheers Phil, I have 1.5 litres of the Motul Stuff :D so no worries there re brake fluid :) Gonna try the bolt holes tomorrow (today!) as I have to go out and get a fine file anyway :) But yes, there are bolt holes on the Jspec (the two small ones) so I'll try them first!!!!! No reason to re-use the disks so last option is no wood ;) Assuming the bolts don't work ;) :D

Aye Gordon, unfortunately I was a muppet and having worked on Pug disks too long, these holes are more associated with securing screws, so I didn't put 2 and 2 together ;) :rolleyes:

 

As I said mate, I'm not a mechanical numpty, nor is my dad who's worked on his own cars for years, but I know where you are coming from ;) I'll sort it ;) :D

 

Cheers for all the help guys - really appreciate it :D

Tighten the bolts a turn at a time on each one and it should pop off.

 

I don’t mean fluid I mean cleaner, a powerful spray of the stuff to wash out any tiny bits of dirt or worse metal.

Tell me about it I was on the M11 when it turned to snow:eek:

 

With your brake lines I would pot some rag in the pipe to stop bits going in and flush hard from the other end when you have finished. Give then a good flush before you try connecting them up to check fit etc. One bit of crap in the system could end up in a major accident.

 

Not wishing to teach anyone to suck eggs here, but you never can be too clean with brake systems.

wasnt you going to do a write up with pics?

 

i have had some uk front set up over a year in shed. never got round to getting them fitted. always thought the jap brakes were good to me. had some new pads in and they feel good.

 

got new uk fronts and stainless steel hoses and going to get the motil brake fluid.

 

first time i felt unsure about brakes was on donningto race track.

 

have fun

I was mate, but when I posted to that effect it seems others had done it twice before and it was never used etc or put in the technical section so I didn't see the point......... :conf:

 

I have to say I had no confidence at all in my Jspec brakes, its quite simply the worse car I've ever owned brake wise, and my Impreza was terrible! so I thought I'd go a bit mad and getting it stopping on a sixpence!

They are ON :D

 

So pleased my 17" aftermarket alloys fit! :D Theres only 2-3mm clearance from the valve - but its enough so they fit snug as a bug :D So, new calipers fitted, disks on (eventually got the old ones off with a couple of M8 bolts as per Ian C's tip - ta :)), Porterfield Fast Road pads fitted, stainless hoses fitted (file worked a treat, cheers dude).

 

Started bleeding the brakes, but got a prob with the kit letting in air, and we'd used loads in the process :rolleyes: so not much left, but I should hopefully be able to reuse so of the new stuff we pumped through today?

 

I still have the rear hoses to fit (already fitted new porterfields there) so will bleed the whole system when thats done as the car ain't going anywhere for now!

 

But one Q. Bleeding brakes, I searched on here and found:

 

NSR, OSR, NSF, OSF - so working to the nearest from the farthest.

 

But found a post from Brian Jackett that said:

 

THis is advice Chris Wilson gave me along with order of bleed:

 

Right Front, LF, RR, LR use full slow pedal presses, allow to return

faster. Keep reservoir at least quarter full at all times, you should

see the colour change as fresh fluid comes out of bleed nipples. Don't

over tighten the nipples, they don't need swing on.

 

So whats the score?

Should be fine, as long as you have bled it into a nice clean container.

I did mine this way, bleeding each one after I had fitted each caliper and disc. I then 'pressure bled' each caliper in turn. That is to have pressure on the pedal and open and close the bleed nipple quickly as the pedal starts to move. Did it about 3 times on each caliper. Torqued the bleed nipples to 12lb/ft.
