Hello All, I had done my rear pads/rotors myself recently, thanks for all of your info. My left front caliper just started grinding. I am looking to buy a reman caliper from discount rovers, but I would like to do the install myself. Any helpful hints or install procedures will be greatly appreciated. Thank you very much for your assistance in advance. You can also email me at [email protected] |

John:
First off, why do you think that a grinding noise is caliper related?
That said, I recently put new rotors on a '94 Disco due to the rotor having cracked severely. Upon inspection and disassembly (OK, maybe in the reverse order!), I discovered that one of the pistons had left its bore (kinda like Elvis leaving the building). As a result, I replaced the caliper to keep my liability insurer happy. The process is nearly as easy as changing pads.
Two bolts hold it to the bracket-14 m/m 12-point. You know how the pads come out. The pipe requires a 7/16" flare wrench (go buy one if you don't have a flare nut wrench-you'll be glad you did). The bleeder I believe is a 5/16". Shouldn't take much longer than it takes to jack the truck up and pull the wheel.
Some will say to rebuild, but for the ease of replacement and modest price, it is hardly worth the time. Shop around, they can be had reasonably, but call Nathan first.

Paul, Thank you. I took it to a reputable brake shop and they said the caliper was not retracting. I am not prepared to try and rebuild myself. It will be well worth the $141 from Nathan to buy the rebuild. Do I need to bleed the line, or is it just as simple as unattaching the old and on with the new? JP |

John,
just one adder to what Paul said - sometimes those 12 point bolts are a bear - they're locttited from the factory so may need a little heat help (propane will do) to break the loctite bond. Sometimes they come right out though.
You will need/want to bleed not only that caliper when you're through, and now is a good time to flush the entire system. So, bleed everthing and push all new fluid through.

I think you must need a longer breaker bar!
First it was the rotors, now the calipers. LOL!
Maybe I'm just more intimidating to fasteners. It's the threat of the torch that gets them loose for me, that's the ticket! Who needs a BFH when you have the blue wrench of death?
It's funny how some of us have no problems with a project and others have terrible times with the same process.

I was lamenting my problem to my System Engineer and I found out that he is quite the mechanic and I relayed the info I found here and he said "no problem, get the part and come over". It will be quite nice to have assistance on this one. Thanks for your guideance!! JP |

Paul - yeah, I was thinking the same thing 
Wierd thing was that on mine - 6 bolts were easy and two were a pain, but easy once a little flame applied! 'course I noticed on the two difficult ones that they were literally covered in loctite - top to bottom (at least it wasn't green)
Go figure?

They must have started that truck before lunch and finished the brakes after lunch at the pub!
Someday, I'm gonna find out which pub it is in Solihull and punch some of those guys in the nose.
I am forever amazed at just how easy my truck is to work on, but then again, I'm the eighth owner and when I tore the rear hub apart to fix a leaking hub seal, I found that one of the PO's had apparently used an axe to remove the hub nut! The bendover (Bob's brother) washer had been through the wringer as well. But, since nothing big has broken yet, I'll keep driving waiting for the next shoe to drop, er, the next part to break:-). |
