StuDoc 72 Posted October 1, 2015 Posted October 1, 2015 You need to wind the pistons out until the disc turns by hand but is slightly stiff. U have wound the pistons right back and then tightened your cable so essentially your handbrake is on constantly but not doing anything. Hence the tight handbrake. Quote
5e colin Posted October 1, 2015 Author Posted October 1, 2015 bugger so i went to far back on the piston pfff rookie mistake ha ha will keep you informed how i get on later Quote
funny onion Posted October 1, 2015 Posted October 1, 2015 when bleeding the back brakes you should pull the handbrake on/off before pumping the foot brake. Quote
StuDoc 72 Posted October 1, 2015 Posted October 1, 2015 bugger so i went to far back on the piston pfff rookie mistake ha ha will keep you informed how i get on later Yes mate thats all it is lol. Loosen off the cable at your lever, whip off the caliper and adjust out the piston until theres a bit of resistance when turning the disc, bolt it back up and adjust up your cable. Just make sure you dont adjust up the cable too much or the handbrake will be on even when the lever is down. Quote
5e colin Posted October 1, 2015 Author Posted October 1, 2015 the info was spot on studoc my handbrake was never as good as it is now i can lock up my rear wheels :) credits to you Quote
H_D Posted October 1, 2015 Posted October 1, 2015 maybe this is why my handbrake is very weak on my ep82 im gonna give this a go tonight too. Quote
5e colin Posted October 1, 2015 Author Posted October 1, 2015 mhhh went for another spin now my handbrake is up higher again ?? is this because i filed off the nipple thats supposed to sit in the groove of the rear pistons ????????? Quote
StuDoc 72 Posted October 1, 2015 Posted October 1, 2015 Its possibly just bedded in the pads slightly also when u put brakes together u cant get them to sit as flush as they would when compressed by a piston you could try jacking it up and either winding the caliper out again or tightening the cable aslong as the wheels still rotate when handbrake is off.That said you shouldnt have filed that off lol might happen repeatedly. Quote
5e colin Posted October 1, 2015 Author Posted October 1, 2015 ha ok wil rotate the pads in the morning and have another crack at it if i left the pin on it i could not get a close tight fit so i filed them down to get a snug tight fit Quote
5e colin Posted October 2, 2015 Author Posted October 2, 2015 small update swapped the pads around so now the niple is in the groove i unwinded them to where they just could not go on the pads then pushed them strait back a mm with a plate with a bolt tru pushing another plate that was lying on the piston so piston cant rotate backwards loose i hope but i think i will have to redo this procedure when the pads are bedded in again ?? Quote
StuDoc 72 Posted October 2, 2015 Posted October 2, 2015 Basically you wind the calipers right back. Then you wind them out until you can get the brakes back together but as tight rotation as possible without them being seized. Do this both sides and while the car is still jacked up tighten the hand brake cable until you get desired clicks. While turning the wheels by hand to make sure they dont seize. Quote
5e colin Posted October 2, 2015 Author Posted October 2, 2015 (edited) did that there again im getting soft parking brake pfff handbrake is pulled right up and lever arms on both calipers are both to the far front of the car brake pedal is solid i cant move the wheels attal then are my calipers fucked ???? Edited October 2, 2015 by 5e colin Quote
5e colin Posted October 14, 2015 Author Posted October 14, 2015 fuck me i just fitted new discs and pads and i still can turn my wheel by hand its hard but can still move it cables are not seized !!! im lost to what the problem is Quote
Johnboy GT Posted October 14, 2015 Posted October 14, 2015 Question as I'm doing the same dude, was there much adjustment on your handbrake cable at the handbrake. My one had about 4 threads before it stripped itself. Waiting on a new one.Did you function the handbrake lever when you rebuilt your calipers to see if the piston pumped out?John Quote
5e colin Posted October 14, 2015 Author Posted October 14, 2015 (edited) calipers work ok when i pull the lever on the caliper the piston comes out my front cable the thread is half snapped of so i have to use a m10 nut under my m6 to get a tat more pull on the cable question when the handbrake is down do the lever go back fully on the calipers or do they stay ingaged a bit ????? Edited October 14, 2015 by 5e colin Quote
Johnboy GT Posted October 14, 2015 Posted October 14, 2015 This is where my caliper sits with the handbrake off bud. I took a photo of my adjuster at the handbrake. I'm pretty sure it's been cut.John Quote
5e colin Posted October 14, 2015 Author Posted October 14, 2015 thanks jhonny i noticed my left cable is 5mm longer then the right 1 so think its stretched a bit would this be the problem ???? i always thought the t section upfront counteracts ant stretching of the cable ??? Quote
Johnboy GT Posted October 14, 2015 Posted October 14, 2015 I'm sure I noticed that the bar on mine was lopsided when I put new cables on. I'll be under it again this week to replace the bar so I'll let you know what I find dude.John Quote
5e colin Posted October 14, 2015 Author Posted October 14, 2015 thanks mate i never came across this problem before maybie i was luckt but i always had good handbrake even with old pads alteast by the time we are finished i will have al new undr there good for the next 5 years ha ha Quote
5e colin Posted October 15, 2015 Author Posted October 15, 2015 (edited) wel lads my cables are free of movement i took them off to check but i noticed 1 is longer then the other 1 also wich 1 gose on what side orange / gray Edited October 15, 2015 by 5e colin Quote
5e colin Posted October 15, 2015 Author Posted October 15, 2015 bummer i just fitted a new front cable that attaches to the t piece its a bit better but i can still turn it by hand altho its a tat stronger ???? still the same problem you know between the pads and caliper there is some thin shims that lay on the pads i dont have them shims on the passo side where my problem is would it be ?? Quote
glanzadude Posted October 15, 2015 Posted October 15, 2015 Orange for passenger side and gray for drivers side. Try tighten the handbrake first and adjust the T section after Quote
glanzadude Posted October 15, 2015 Posted October 15, 2015 The two rear hb cables have different part numbers so that tells you they are different Quote
