Suddenly got a loud metallic screech from OS front wheel whilst reversing down at the allotment today. Disappeared after driving forward a few yards.

Grimdog Yes the rears can't be replaced without removing the hub and that means a new bearing doesn't it.

That's the next question- what is the downside of not re-fitting the dust /mud shields ? Jules |

They are there to reduce water splashing up from the wheel on the opposite side of the vehicle from contacting the rotor. However the chances of that happening is low, and any water would steam off instantly the brakes are applied. The rest of the time, the shields reduce airflow over the rotor, so they heat up quicker.

My drivers side broke free of its mountings last summer and is currently sitting in the garage. It just fatigued around its mounting points. Plan to weld a little tab onto each and re drill them. Will wait till next set of front pads and discs required as easier to get at the fixing bolts with the disc off. Landrover - turning owners into mechanics since 1948

Nor do they usually last long enough to go rusty Jules |

Well that is worrying! I've had both rear wheel bearings replaced in the last year and have been told that I will need new rear back-plates for its next MOT (in October)... I'm not sure I want to pay for both rear bearings to be done again, just for brake back-plates. Could be bye bye to the FL2 in October if I can't find a way around this, but at 200k miles it's probably not worth that extra expense. 2005 D3 2.7 Auto Previously: 2010 MY FL2 TD4e GS - Now gone at 199,500 miles, about 135,000 of them mine. ‘93 Defender 110 200TDi CSW ‘87 Defender 90 4 cyl Petrol ‘83 110 CSW V8 - best ever!

The problem with the rears is that a spring from the handbrake mechanism (iirc) attaches to it. When one of my rear shields rusted away the mechanic managed to find somewhere else to attach the spring thus avoiding replacing the shield. The car has successfully passed a mot since. |

The springs just attach each brake shoe to its partner. There are some small pins which pass through the backplate, secured with a clip which hold the shoes to the backplate.

I always leave cars in gear as a matter of course, having once had one with a dodgy handbrake. This solution looks more substantial than that though, although it’s a while since I saw it. |

My (2014) has the EPB so no drum brakes, and therefore no drum brake back plate. It has a mud shield very similar to the front C shaped mud shield, so should think it can come off (when needed) without removing the hub. Jules |

Is having no front disk brake mudshields an MOT failure ?
