Thought I'd start a new thread for the front brakes. 
So far we've removed the front callipers. As noted previously, no brake fluid came out of the hoses when we disconnected them but there was some fluid in the actual calliper. The brake pedal, when depressed, still no fluid out of the hoses? Managed to remove the front pads. Couldn't remove the brake pistons from the callipers but with some degree of force was able to push them further back into the caliper. If the brake pedal had been working I would have connected them back up and seen if they came back out again but for the moment they've been sprayed with WD40 and left.
So, does anyone know a trick for removing the pistons?
If we can remove them the plan was to buy two of these and reassemble, www.ebay.co.uk/itm/Repair-Kit-brake-caliper-Front-ATE-AUTOFREN-for-DAF-44-44-Estate-/171436779764 Does that sound like a reasonable idea?
This is the first time my dad and I have done anything this mechanical! |

Have a word with Sreve Bidwell. Can't remember the details precisely but I bought a pair of new callipers from GSF. Not for the DAF (vw I think) and not the prettiest of castings but darn cheap and new. Probably less of a ball ache to swap them over then recon what you have. If you do recon yours then I'd be tempted to fit stainless Pistons, no more worrying about rust seizure.

IIRC VW Beetle calipers fit, the pistons are marginally larger but it should not make any difference. Pad sizes are the same.

So, does anyone know a trick for removing the pistons? Plenty of vids on YouTube to help you: If it's being stubborn, then air won't cut it. Adapt a grease gun and pump 'em out with grease. You're going to have to clean it all up anyway, so grease isn't going to be a big issue as long as you remove ALL of it before reassembly. Those are the right kit as far as I can see (although they don't do the DAF 44 as they have drum brakes up front and they don't do the 66 base and 66 luxe as they have drums too). Now it's only a reasonable idea if the bores and pistons are good. If they are manky then it's time for a fresh piston. If that's the case you might find it easier to send them off to get refurbished Best approach would be to disassemble and see what you have. Price up what you need (just seals or piston too) against the cost of refurbishing/exchanging the calliper. There might not be all that much in it. Avoid using VW callipers of the same family as they are a different bore size (40mm?) and will change the front/rear balance (amongst other things / all other factors being equal). The other thing is the VW ones have a different hose entry point, so the original hose length may not apply. However, if you think you know more about it than the engineering boffins that designed and tested the car, and can do the sums, then go ahead and fiddle. |
