Guest zedex Posted June 4, 2003 Share Posted June 4, 2003 Hi Fellaz, My brakes on my Z feel weak, slowing down seems to take some time, not good - trust me. Any ideas why & what can be done? (Discs, pads are ok) Cheerz!!! Quote Link to comment Share on other sites More sharing options...
b19rks Posted June 4, 2003 Share Posted June 4, 2003 I think that is what most on here would describe as the norm on zed brakes, ie crap. Ive never had any trouble with mine even managed to outbrake a porshe once when we both booted it over a hill into stationary traffic. You may have a piston or two seized up in the calipers, if you remove the pads, with the top off the resevior you should be able to push the pistons back quite easy, if you cant try giving them a good clean up, if that fails it might be seals or calliper time! Good luck Quote Link to comment Share on other sites More sharing options...
shaunmac Posted June 4, 2003 Share Posted June 4, 2003 I've taken out the pistons before today and cleaned them and the cylinder which is usually fouled near the rubber piston seal. If they're really dirty, you might need to use a very fine grade of sandpaper, say 1200 grade but don't sand them too much! It might save you having to buy new calipers anyway. You can get very seized pistons out by jamming the good ones with a suitable object and getting someone to press the brake pedal hard to push out the awkward one. The trick is to get all 4 out a good way out so when one pops out, you'll be able to pull out the remaining three as you'll no longer have any hydraulic pressure once one falls out! Good luck Shaunmac. Quote Link to comment Share on other sites More sharing options...
Guest andyduff Posted June 5, 2003 Share Posted June 5, 2003 Could be the brake booster circuit. Are all the hoses to the master cylinder from the upper intake in good condition? May be a clogged check valve too - they seem to fill up with the crap from the breather system sometimes ;) HTH CheerZ, Andy A seized caliper will almost always give uneven pad wear. If all pads are wearing square and evenly then I'd say it was less likely to be a sticking piston. Quote Link to comment Share on other sites More sharing options...
