This is going to sound like a daft question, but not had one of these metal "spring" bits on brakes before ....  IMG_20210321_132540_9 by David, on Flickr How does this work? does it just need to be levered over? is there one both sides (been so long since I have done any vehicle maintenance  ) |

They can be a little stubborn to get off, prise away with a screwdriver where the clip looks like it disappears into the Caliper surface . The clip,should come away . It will be a bugger to get back in as it’s under tension. here you go ..... |

Thanks Bob  I watched that after you posted it and after the parts arrived yesterday, watched it again this afternoon in readiness to give it a shot tomorrow morning. Looks fairly straightforward and I even have a brake piston windback tool (needed it for the VWs) so a better option than a pair of waterpump pliers  |

Pair of wide grip pliers and they pull straight out. The springs tension holds them in place 👍

Trying hard to see what the spring actually does, mins.......elaborate please....? according to the guy in the video, it is an anti-rattle tension spring. on the inside pad, the pad actually physically fits into the piston. I honestly don't understand how it is possible to get a complete kit of discs and pad delivered to the door for under £45? You have the sellers fees to Ebay and Paypal, their time packing it it up, their courier fees, and what is left has to provide the profit AND cover the cost of the parts. really is remarkable. |

Did the brakes this morning. Actually pretty straightforward 
New Brakes on Corsa by David, on Flickr The spring was easy to remove but as Bob warned, a bugger to get back into place The slider bolts were very clean. The only contamination was some sticky dirt on them at the point they are exposed outside of the boot, but I cleaned that off anyway The pads had loads of meat on them and nowhere close to worn (and pretty good for under 20,000 miles), but the inside surface of the discs were definately bad. I am sure it is a consequence of the car sitting and hardly used with the brakes gluing themselves to the disc. Think I need to get it on the road on a weekly basis in future! Next step - test drive and book an MOT Retest |

Love that low pad warning device......will be worse than chalk on a bliddy blackboard.....! Wife would hear that noise for months then tell me the night before its MOT.

I used pliers to do it and it was not ideal, but after a few goes it got in. I have a pair of little mole grips as well and I think they would have been perfect if I thought of it!

Back for the retest today. Had to hang around for literally hours and hours so they could find a time when the test kit AND tester was free, but eventually around lunchtime ....

Andy is barking up the correct tree. We used to think of warped discs as being like an old 45 record but in fact they tend to wear thick/thin and as a result transmit that back through the fluid to the pedal. It’s proper name is DVT (nothing to do with long plane journeys). It’s stands for disc thickness variation. The easiest way is bin the discs (they could be skimmed but it should be done installed and it cost nearly the same). I tend not to get too wrapped up in price or brand. Any of the well known makes will meet “Reg 90” which assures similar performance to the originals. To put it bluntly, brakes don’t like lockdowns. They are sat outside in all weathers with nothing to do but go rusty. Before you know it they get deposits and clear patches then you get that depositing that Andy alluded to. All new bits Hoovie and get those pins sliding like the big man says and you will cure your problems..... until they do it again. Brakes need work, the more the merrier! Reading that doesn't fill me with glee.....So is there any advice to those who have summer cars ? Like my wee MX which sits for months ? What I do is occasionally wash the car then take it for a drive to warm/heat up the brakes and remove the light rust from the disc faces. Should we lightly use the brakes of give them a proper workout ? Or does it make no difference ?? |
