I have a 92 RR SWB that has brake issues, specifically the antilock system and the master cylinder. For some months before I put the car into retirement, it was leaking brake fluid from the bottom of the master cylinder. I would top it off with fluid periodically, and all seemed OK, but the problem persisted/worsened. I took it to a dealer who shook his head and said: � The master cylinder needs to be replaced � If you replace the master cylinder, you pretty much have to replace the whole antilock system � Parts will be around $2,500, and total job will be $4,000 - $4,500 I am not much in the mood to devote that kind of bread to a 12 year old car with 120,000 miles on it. I am thinking that perhaps; � The dealer may be overstating by a bit � Replacing the master cylinder may be all that is really necessary, as there was no evidence (to me) that the rest of the brake system is faulty � Given the location of the master cylinder, under the hood but accessible right out in front � This sort of job may be within my capabilities � I have plenty of time to tinker with it Does anyone have any suggestions or reasons I shouldn�t plunge into this? | ||

You may be able to just get a seal kit to refit the reservoir to the MC (??) If not, replacing the entire valve block is not that hard - just remove all brake lines - unbolt the valve block from inside and pull off - refit as opposite. The longest time is bleeding the system. A workshop manual is needed because of the very specific order in which you must bleed the 12 or 13 bleed screws. A pressure bleeder is great for the RRC systems - makes life very easy. Used valve bodies go for $100-$300, so if you must replace it, that should be your total investment other than time and brake fluid (plan on about 3 quarts). Unless you have a problem with the pump, accumulator or pressure switch, there is no need to replace any of that. It is not difficult - just tedious. Good luck Bill | ||

Oh yeah - you'll have to move the pump out of the way to remove the valve block, but that's no big deal - though the rubber isolators used to mount it are usuallly rusted completely and break whem removed. Bill | ||

It is just like legos ( covered in brake fluid) You can try to replace the seals in the MC with a kit or order a gently used MC and or valve block from rover cannibal or Will Tillery et al .. It's old and it sounds like it isn't your daily driver so try the seal kit first as that is easiest and cheapest. Give it all a good bleed after that and you might be good to go. check out spanishtrail land rover site they might have some photos on how the bleeding is done. The dealer has to replace everything with new parts for liability reasons so stay far away from them! |
