seeing as the vw market is geared up to leave as little in your walet as possible, the lack of a big vented disk kits for the rear of a beatle would lead me to think that one isnt really needed. My civic has disks all round fairly good sized vented ones on the front an small solid ones on the back. The fronts do most of the braking. Now it could be all different for a rear engined car but given the weight of the car id have thort the original drums would have done. Dan

If you hadn't already bought the Porsche bits, I'd have said don't bother! Front wheel cylinders in the rear drums will even up the balance in a light car like a Fugitive. Just thinking aloud here - why not get the wheels redrilled to Porsche pattern rather than the hubs? There should be plenty of material I'd have thought - there certainly was on the slots on my old buggy. Personally, I'd shift the slots on and look for a set of Cookie Cutters in 6" for the front and 7" for the back - they're not that popular in Porsche circles so a set shouldn't cost you much more than £150ish. A pair of skinny slots could cost double that!

This week Tom is away with school but I'm going to try and get on with some electrolysis again! Having recently been using both I would highly recommend using Citric acid (depending on size of components) it'll work magic on those brake parts. (see my build thread or luckyseven 's)

A pair of skinny slots could cost double that! You both make very good points, but the whole project is about Tom learning skills, so in some ways the end result is less important that the journey to get there (except if we don't get to the end.... that will possibly snub any spark of interest, and if it's dangerous that's not great either.... so now I think about it, the end result is quite important too ) so the Porsche brakes are good because we learn about manufacturers sharing parts and easy upgrades (and they cost us about 11 bags of scrap, the discs will be another couple each...) The machining can be done by Denis, who's a toolmaker who lives next to my folks..... and has a shed full of machines (and another skill experienced) and if not, if I can get Tom inside a unit and the engineer talks to him then it's worth paying Weirdly enough, we will be taking the drums apart and having a play with them before getting rid, because it's useful to at least know about them (my daughter has also been told she's got to come and work on various parts of the car, and brakes are one of those parts.... she has no interest in the project but I hate the thought of her being ripped off by a garage somewhere because she is scared of the jargon!) It may be worth redrilling the wheels, but type 3 hubs are £30 so may be cheaper to go that way..... but worth thinking about I'm not sure 6s and 7s will give us the look we want..... if we had a coffee table, and my wife let me keep any of my stuff in the house, this would be on that coffee table (but instead they are by my bed) I don't know if that makes it sound like a money-no-object build, which it isn't, it it does have a revenue stream that means we can invest as we go (I maybe get £1000 of scrap a year, which we can put towards this) so the longer it takes, the more cash we have to spend legitimately :/ And because Tom has to help sort the scrap and bag it up, he is also learning a work ethic too (hopefully) Also hope that doesn't make it sound like I'm not listening! I'm open to all suggestions, I think I'm maybe just explain why we may not action them

I nearly bought some citric acid from ebay when I read your post. As per my above post... I now have too, or I'm hoist by my own petard We didn't seem to do that well with the electrolysis, bug I think some of the connections weren't great, so will have to have another go at that as well John

I got my Citric acid from Amazon, £5.25 for 1kg I use it 250g at a time (cleans 2 calipers and 2 discs). My experiments with electrolysis were variable, as you experienced connections were an issue if I do it again I'll investigate on some better connections and a better power supply. Mark

John, I get exactly where you're coming from, and if you've got a local friendly engineer who will talk Tom through processes, you're quids in in the future. I don't have that so I'd be paying much more! Continue onwards and I'll watch with interest!

Love what you are doing and why. One thought on the brakes, completely get that with 75% of the weight behind you even with weight transfer you still have a good chunk more rear brakes required than a front engined car. Back in the day I was looking at converting my skoda rapid to rear discs to get rid of the brake fade. What stopped me was handbrake efficiency/ cables. Front wheels locking first is also a lot safer. Are the Porsche discs smaller diameter and smaller calipers than the front discs to keep a forward brake bias ?Would type 3 drums an option ? Just musing on your behalfs ! Keep up the good work and updates. James

I had previously given your parenting skills and eleven out of ten, I'm afraid that I have been forced to re-evaluate that rating, and I must, with regret, inform you that I now have to change that rating to 14 out of ten...... ;-)

We've been out cleaning up the rear suspension arms and brake parts.... Compared a beetle arm to the cleaned 944 one And played spot the difference.... Which seems to be the size of the pivot bush! Started cleaning brake parts with citric acid... And have had good results, after a couple of hours And after a couple more So will have another look in the morning.... must say citric acid seems easier to work with, you can just drop parts in the bucket without having to check nothing is touching etc And Tom approves of the slots! So we sorted the scrap out, and I'll weigh that in this week to give us some cash to take to Stonor Park next Sunday... see if we score a few more bits whilst having a look around!

Thanks 24 hours later and the brake parts look nearly like metal.... we had another scrub and dropped back in the tub... but they are so much better! got to this; just need to free the pistons now, any suggestions?

great progress....
some folks cover the "out" side with a towel and blast some air through the inlet side to force the piston out...
it can pop out with some force...though I have found it just sorta pops out....

or screw grease nipple into inlet pipe fitting, pump full of grease and force pistons out

I use a foot pump, and a little bit of hammer and punch persuasion.

Managed to get the pistons out, stopped in at a mates, and we squeezes the pistons in a bit and then they twisted out (that won't work with the fronts though!) one piston is lovely, the other has some pitting Then gave the bits a final scrub (and because the wife was walking the dog, dried them off in the oven!) We then gave them a coat of primer And then some brake caliper enamel, in the colour Tom chose! I thought it would be easier painting it on rather than spraying, but it doesn't give as good a finish.... so once it's dry I may revisit it! I managed to get some discs, as Euro car parts had a discount code at the weekend And the type 3 hubs turned up So I'll need a spacer for behind them (19mm I seem to remember) And then we need to fit an arm back on the buggy and work out offsets before going too mad... But we couldn't get the hub nuts off at the weekend, hindered by the fact that they aren't bolted to the car.... so I've bought myself a tool (not from the budget, as it's a tool for me!) it's a torque master, bolts to the hub and then gives a 9 to 1 advantage, will be trying that before the weekend Off to weigh some scrap in, in the morning, so we have some funds for the weekend

Funnily enough, was just looking at some seals of his on eBay! Thanks!

Definitely recomend them, ive used them many times and always been happy. If you can afford the price hike put stainless pistons in no corrosion fit and forget. Dany
