Noel Posted September 4, 2006 Report Share Posted September 4, 2006 I know ... i know.... Look at the lip on the edge of the disc.... must be close to 5mm so they just kept putting on new pads and thought the disc would last forever?

Tony Posted September 4, 2006 Author Report Share Posted September 4, 2006 they forgot to put the wheels back on Without wheels you don't need brakes....... so no incorrect Quote Link to comment Share on other sites More sharing options...
Bazza Posted September 4, 2006 Report Share Posted September 4, 2006 what about a clue Quote Link to comment Share on other sites More sharing options...
Noel Posted September 4, 2006 Report Share Posted September 4, 2006 what about a clue Can anyone see a problem... The symptoms are no brake pressure on the initial pump..... but pressure available on the second pump....Your thoughts. The disc is so worn down it has a 5 mm lip, hence the reason there is no pressure on the first pump is because the pistons have to travel so far ....... or am i wrong Quote Link to comment Share on other sites More sharing options...
discount tyres dan Posted September 4, 2006 Report Share Posted September 4, 2006 i just noticed something else.. is there a problem with the hub nut in the lower picture.. it seems to have the outer cover missing, the top one looks new and so do both lower arms..

The disc is so worn down it has a 5 mm lip, hence the reason there is no pressure on the first pump is because the pistons have to travel so far ....... or am i wrong In your example the peddle to remain soft until the new pads adopt the shape of the worn disks, but i see exactly where you are coming from.

Adie Posted September 5, 2006 Report Share Posted September 5, 2006 And the answer is ?????????????????????? Quote Link to comment Share on other sites More sharing options...
star a Posted September 5, 2006 Report Share Posted September 5, 2006 in the bottom pic, the lowermost spring is incorrectly positioned allowing the outer caliper to move away from the disc.. Quote Link to comment Share on other sites More sharing options...
Tony Posted September 5, 2006 Author Report Share Posted September 5, 2006 looks like a lot of copper grease there ? is the spring in the second pic fitted wrong at the bottom Winner...... yep the NSF rattle spring is incorrectly fitted... What we have is a floating calliper and a rattle retaining spring that is meant to pull down on the calliper with the spring captive under the caliper carrier. This chap had fitted the spring in a fashion that lifts the caliper when not braking, pushing the piston back into the caliper, hence the initial loss of pedal pressure.... I was dealing with this via email prior to seeing the car and i admit i was in 'heady scratchy world' until i saw that spring.... then i was in 'no wonder world' Well spotted Master B. and indeed team wim Quote Link to comment Share on other sites More sharing options...

discount tyres dan Posted September 5, 2006 Report Share Posted September 5, 2006 i had a similar problem on a peugeot 406 estate today, except on the rears, the rattle spring is suposed to sit on the inside of one pad and the outside of another. the car came in with no pedel on the first pump then good brakes. because the clip was inside both pads. pushing them back towards the caliper and pushing the piston in.
