Rear disc brake options

[kellymoe]

What is available? Anyone here done it?

[Mike Hippert]

DO you have the Rover rear or Sals rear? THe Rover rears come with Discs on 90s, and I know you can get discs for the Sals, as Yousef has Discs on his.

[kellymoe]

Mike,

Yes it is the Rover Sals. The 90's did not come with a Sals did they?

[flippedrover]

Nope.

[Mike Hippert]

Talk to Keith at Rovertracks I bet he could set you up with a set.

[kellymoe]

Mike,

Thanks. I will do that.

A friend just did a 110 rear disc conversion. It was a complete bolt-on using all standard LR parts. When you add it all up, it's quite pricey. I think the most economical option may be to get a used disc brake Salisbury axle from someone like RDS. If you want a built HD axle, then yeah, check out RoverTracks. Here's the parts my friend used:

1 FTC1725 Axle shaft LH
1 FTC1724 axle shaft RH
2 FTC4785 hub seal inner
2 FTC5241 washer key front axle
2 571752 drive flange gasket
10 BX110095M drive flange bolt
2 FTC3179 lock washer
4 RTC3429 hub bearing
2 FTC3649 stub axle gasket
2 RUC105200 drive flange
2 FTC942 hub assembly
2 FTC1740 stub axle
2 549473 circlip
10 FTC1368 bolt, rotor to hub
1 SMD100260 mudshield LH
1 SMT100270 mudshield, RH
2 FTC3846 rotor
1 SFP000280 brake pads
4 FTC3375 caliper bolt
1 ANR2779 brake pipe
1 NTC7964 brake pipe RH
2 FTC3306 caliper bracket
1 STC1268 caliper RH
1 STC1269 caliper LH

Ryan,

Can you get your friend to give a report out on this conversion? Any issues since? How's performance changed, and local parts sourcing? this is a great list. I'll bet some of these parts can be sourced used, and some appear to be shared with Range Rover Classics.

[evilfij]

I wonder if you could do it using disco hubs and disco shafts? EDIT: those hubs are just standard rover ABS style hubs, I have them.

I have a brand new set of rear calipers if you need those.

Follow-up Post:

It looks like you have to buy new shafts with flanges (assuming disco I ones do not fit), stub axles (spindles) and caliper brackets, everything else looks like it crosses with D90/disco/RRC parts commonly available used (some brake part numbers (like rotors) are different but I think they are basically the same)

[Bowtracer]

call Keith he has the parts you will need. or knows wha is needed. I looked into it a while back
its not that bad the most expensive part I remember is the cals

[Red90]

It is not going to affect performance. Drums and discs give the same performace when both are in good conditions (on these vehicles in the rear). The downside of drums is that usage in mud wears them fown faster.

[Bowtracer]

The drums I have work great BUT you have to keep them adjusted. with that said the masters seem to leak frequently. ooh well they are cheap
i added vented rotors & cals to the front & she stops scary fast now

Mark,

The conversion was done for a customer so the guy I know doesn't have daily use of the truck. And the parts were all purchased new from the dealer so hence quite expensive. If you're able to track down used parts, it may start becoming cost-effective. It looks like Ron has some of the interchangeability figured out so that would help in finding used stuff.

I wish I knew how the rear discs affected performance, but I haven't heard anything. I don't think there's been any problems, but I don't know how much it's improved the braking. I'll know eventually as I'm getting a used disc Salisbury from the UK. However, I probably won't get it swapped over until the end of the year.

are the current 110's on sals or something else, seem like the last (newest 110) I recall was the CKD on RR "axles" perhaps I am wrong. Would it be hard to convert to what the new (er) 110s are using?

[thewap]

seems like most of the parts in that list are interchangeable with the D90 (except axle/CV) and are not mandatory for the swap if in good cond.. I would imagine the key parts for the swap would have to be the Caliper mounts, Calipers, rotors ,pads and brake lines. The rear calipers are cheaper than the front.. (single piston vs double piston). I wonder how the double piston (frt.) caliper would feel on the rear of the NAS..

Current model 110s use Rover style rear axles. Since around 2004, I think.

Scary, I think, is the word that would spring to mind :rolleyes

Do your brakes suck that bad or what!

[Overlander]

I hear the rear drums work almost as well as discs on the 110. I'm interested in the maintenance benefits. I had a 79 Jeep CJ7 with front discs and rear drums, and the rear drums SUCKED for maintenance!

[mikeslandrover]

I put the larger 110 front calipers on my early 90 and a Classic Range Rover axle complete with discs on the back. That set-up stops things fine, and maintenance is much easier. My 110 has rear drums but rarely gets off raoded and I've used 1 set of shoes in about 90,000 miles :cool:

[thewap]

[Do your brakes suck that bad or what!]

My brakes are pretty good all around. On the road most of the braking force is transmitted to the front. So double piston makes sense. Double pistons in the rear I don't think would make much difference on road. But did you ever get that feeling in your gut when you have to back down a steep incline? I have, and I was wondering if double piston calipers would make a difference when in that situation.:)

[Bowtracer]

hand brake!

[thewap]

[Handbrake!]

yes! last resort back up :eek:, no modulation though..

[newfD90]

I just had my 110 converted last week. HUGE difference. I love how this thing stops now. Granted, I had a leaking cylinder, so I used that as an excuse to change to disc. :) Even the Wife could tell a difference. Talk to Keith at RoverTracks. He hooked me up with the right parts list and brackets and the guys at Pikes Peak Rovers did the excellent work. Using a combination of used RRC and Disco I parts, it was cheaper than doing the Zeus kit.

[Overlander]

Chance,
Now that's good information. Sent Keith an email. Thanks. (you wouldnt' have that parts list, would you?)

[newfD90]

Now that's good information. Sent Keith an email. Thanks. (you wouldnt' have that parts list, would you?)

I'm pretty sure this was the final list of parts (it morphed somewhat during the conversion). I'll double check, but meanwhile:

Pre-ABS RR Classic hubs (front or rear). '89 or older I think.
Factory OEM Salisbury Disc brake brackets from Rovers North with .100" machined off the caliper mounting surface
Rear calipers from either a Disco I or D90
Rear rotors from a Disco I or D90
Brake pipes from a Disco I

I opted for all used parts except for the the consumables (rotors, etc) and the brackets. Thanks again to Keith at RoverTracks and Eric at Pikes Peak Rovers!

[evilfij]

I have everything but the brackets. I will give it a shot.

[ECR]

Switching the front of a NAS 110 from solid to vented rotors is a better benefit in my opinion (for braking reasons mentioned in the post). You can install D90 front rotors and calipers as a bolt on. The rears maek life easier, but you won't see too much improvement if you just do the rears (some, but don't expect miracles).

[Overlander]

so bottom line, do both front and rear upgrades. Sounds good. thanks all.

Does anybody have part #'s for the RR hubs and salisbury brackets that I can reference? The rest is easy-breezy to find, but dont' want to "F-up" those 2 pieces.

[newfD90]

Forgot that Keith mentioned the bolt-on upgrade to the fronts. I figure I'll do that when it's time for pads. Also forgot to put Disco I Dust Shields on the above list.

I'll check my receipt, but I don't think part numbers are on it.

[evilfij]

I have a couple of spare sets of RRC non-abs hubs if anyone is in need.

Other than the new Disco I rotors, no part numbers.

What's your thought on the D90 front calipers vs the stock 110 calipers? I will get new vented rotors either way but have a set of front D90 calipers; should I stick with the stock 110 calipers on there or swap the D90 ones?

[sflash868]

When you guys are saying vented, you're not referring to cross-drilled, right.

Hmm... and this just bolts straight onto the Salisbury rear axle.
What drive shafts do you use? The Salisbury ones?
And the drive flanges??
This sounds interesting, most of the parts are dead easy to come by over here, except for the brake brackets does anyone have a part number for those?

I guess my question is does a 110 vented disc exist that is a direct bolt on replacement for the solid version. I'm guessing not since the vented disc is probably wider.

[JimC]

Based on my inspection of a vented disc caliper versus a standard caliper the only difference is a metal spacer between the caliper halves. I dont know if rover sells the spacer, but I've seen them somewhere.

[WhiteD90]

Keith says RDS has the spacers and longer bolts...

The above list were the only parts changed. The only issue was milling 100mils off the bracket. Unfortunately, I don't have the part number. Keith (revor) might know it.

Keith confirmed it is the part number listed FTC3306 as stated by mikeslandrover

[Antichrist]

I wonder how the double piston (frt.) caliper would feel on the rear of the NAS..
They wouldn't fit without modifying the axle casing because the mounting holes are furtner apart on the front calipers.

[sflash868]

Has anyone ever tried fitting calipers from another make of car? I know everyone under the sun on Roadfly throws Porsche Turbo brakes on BMWs, VWs, seen it on a Camaro, Lotus etc. I just eyeballed it but the mounting holes of the D-90 caliper are pretty lined up compared with the ones from a caliper off an 89 porsche turbo. Just think of all the pad compounds I could have!! On a side note.. I had a chat with a guy from Stoptech. He said that if someone is willing to pay enough they will make a set of floating rotors for a d-90. I don't know about a 4 grand group buy but interesting none the less.
