Ragazzi qualcuno sa dove li posso trovare questi pistoncini delle pinze posteriori originali Brembo della Elise s1?

Le pinze posteriori duvrerbbero essere Renault 9 quindi dovresti trovarli da qualsiasi ricambista

Renault 9 sicuro? Mmm do un'occhiata su internet se trovo qualcosa

Si e anche Viper del 1997.

Su Elise parts vendono il kit per rigenerare la pinza, ma effettivamente non ho mai visto i pistoncini, sarà perché di solito non si rovinano???  scratch scratch

Che ti devo dire, sembra proprio cosi!!

Erano quelle posteriori, e comunque si parla della vecchia Viper prodotta dal 1992 al 2000!!

Sono rimasto colpito pure io che usassero una pinza come quella su una Macchina americana cosi pesante e potente.

Una supercar che nel 1992 avrei voluto comprare.

1. Give me a little Brake

2. Ugly Duckling Brakes

3. The Little Brakes That Could

(The original article is here: http://40mmbrakes.auto.officelive.com/history.aspx)

What do a 1988 Renault Alliance, 1992 front wheel drive Dodge Monaco, a Lotus Elise, and a non-ABS Gen 1/2 Dodge Viper have in common? Would you believe the rear brakes?

PISTONCINI PINZE POSTERIORI BREMBO ELISE S1 Brembo_Caliper_1

When Bob Lutz, Tom Gale and Francois Castaing created their vision of a supercar, they explored the contents of the Renault parts bin, where Castaing had been technical director for motorsport programs. Renault used a Brembo single piston disc brake caliper that cleverly incorporated the parking brake and eliminated the need and weight of an additional secondary brake. The unit is small and compact, and actually weighs less than the aluminum 4-piston Brembo caliper on the front of a Viper.

To reach over the much thicker Viper brake rotor, the casting was stretched almost a half inch, but otherwise the mounting hardware, internal parts, the 36 mm diameter brake piston, and all replacement rubber parts were the same.


Internal parts?

PISTONCINI PINZE POSTERIORI BREMBO ELISE S1 Brembo_Caliper_1


There are quite a few internal mechanical parts to enable the parking brake to engage and disengage, clamp tightly on the rotor, and to advance the piston when the brake pads wear. For smooth operation and long life, the parking brake arm rotation advances the piston against a needle bearing supported thrust washer. Pulling on the parking brake handle rolls three ball bearings up internal ramps to provide tremendous mechanical leverage and act like small doorstops to keep the parking brake engaged. The rod that actually forces the brake piston against the pad and rotor is threaded so that each application also adjusts the system for pad wear. The rod rotates easily by rolling on a 6-ball caged bearing. All of these parts are internal, bathed in brake fluid, and held captive by a snap ring in the piston and another deep in the casting, requiring both the caliper and piston to be significantly deeper than a non-parking brake caliper.

The caliper is mounted to the upright with two bolts. The larger M10 hex head bolt (15mm socket) rides inside a greased, steel sleeve to keep the caliper floating perpendicular to the rotor and to absorb the torque when applying the brakes. A smaller M8 socket head cap screw (6mm allen) also runs through a steel sleeve, but with a rubber guide and an internal Teflon slide.

Together they align the caliper for even pad wear and allow the caliper to slide side-to-side as the brakes are applied and released.

There are some particular service concerns to pay attention to. The intricate internal parking brake parts are susceptible to rust and may experience some sticking when water inevitably sneaks into the system. Flush your brake fluid regularly.

Also, the rubber boot protecting the inner end of the greased steel sleeve is frequently abraded by brake pad material, and without protection from the elements, the side-to-side sliding action can get rough and cause unusual pad wear. As with any brakes, track use will often harden the piston dust boot, allowing road grit between the piston and seal. When the dust boot can’t protect the piston, leaks are only a matter of time.

PISTONCINI PINZE POSTERIORI BREMBO ELISE S1 Brembo_Caliper_3

So what can you do if your calipers need a little TLC? Don’t look for help from the service manual, there are no instructions! Your friendly Dodge parts manager can’t help either, since individual parts are not available. Your only option through Dodge is to purchase the complete caliper, which carries a list price of around $450.





Servicing

UK Parts

A Brembo slider repair kit is available from Renault dealers (part number 7701205496) for £30+VAT. A piston seal kit is also available (part number?) and complete kits that include everything. Bleed nipples are 10mm and common with most Ford calipers (available from most motor factors).

US Parts

The Do-It-Yourself secret is to ask for Renault parts! If you need a dust boot, look for Auto Specialties part KC-83017 (about $6). For the mounting bolts, slide boots, and other external rubber parts, ask for the Mopar brake attaching kit PN 4423504 (about $70.) The OEM 36mm piston seal is Brembo part number BRE05.5955.56 (around $11.) For internal parts, purchase a remanufactured Dodge Monaco caliper for around $100 and transfer the parts needed over to your Viper caliper. Make sure you get the side you want – the left and right calipers are mirror images inside and out!

If you drive with the spirit that the Viper was intended, you may have noticed how often one or both of the front tires lock up and slide. Unfortunately, for all the engineering that Brembo put into the rear brakes, the Renault-size brake piston leaves the brake bias excessively towards the front. Testing in a 1994 RT/10 showed that with the front tires doing most of the work, braking performance was limited to a tepid 0.8 G’s before skidding. Not very super performance, is it?

Upgrades

To improve a Viper’s stopping capability, you don’t need to spend thousands of dollars on massive 4-piston rear calipers, permanently cut up the rear suspension upright to make them fit, adjust them with an add-on proportioning valve, and give up your parking brake… although it would look great (and weigh more!) The OEM calipers can be bored out to a larger size (just like an engine block) and the pistons can be sleeved to fit (as is done in auto restoration efforts.) The casting accommodates a “plus two”-size larger 40mm piston (Brembo parts come in even sizes, so 36mm to 38mm to 40mm is two steps), which increases the rear brake clamping force by 23%.


PISTONCINI PINZE POSTERIORI BREMBO ELISE S1 Brembo_Caliper_4


This nicely complements the front brakes and allowed the same ’94 RT/10 to improve to over 1.0 G’s braking using the same brake hoses, pads, and mounting hardware. It is an easy two-three hour job for the DIY owner and retains the stock look, fits under the original wheel sizes and is externally undetectable. Best of all, the testament to “this is how Viper brakes should have been from the factory” is that they do not add points in the Viper Days Clas Matrix.


PISTONCINI PINZE POSTERIORI BREMBO ELISE S1 Brembo_Caliper_5


The oldest Vipers are now approaching their 15th birthday, so it’s time to start preparing for the inevitable round of gathering hard-to-find parts. If you have any caliper questions, need sources for those small missing or broken brake parts, or are considering a rebuild or resize, share your questions and answers on the Viper Club website forums. My display name is Tom, F&L GoR and I’ll be happy to help. And yes I wish they looked nicer, but as ugly ducklings they can still do the job!

Cosa le pinze oppure i pistoncini?

Qui comunque spiegano come rigenerare la pinza Brembo:

Repair

The service manual claims the Brembo Calipers fitted to the rear brakes of the Elise are not fully serviceable.

These instructions were developed by disassembling and reassembling many calipers and are not perfect.

The Lotus Elise rear caliper is sometimes criticised as being too small. The rear caliper can be machined to accept a 38mm or even a 40mm piston and sleeve.

For the 38mm piston, you will need a Brembo 38mm seal, part number 05.5955.57

For the 40mm piston, you will need a Brembo 40mm seal, part number 05.5955.58

This conversion still allows the use of all the other standard size parts that come in the KC-83017 kit


Riparazione

Il manuale di servizio sostiene le pinze Brembo montati i freni posteriori della Elise non sono completamente riparabile.

Queste istruzioni sono state sviluppate da smontare e rimontare molte pinze e non sono perfetti.

La pinza posteriore Lotus Elise è talvolta criticato in quanto troppo piccolo. La pinza posteriore può essere lavorato per accettare un 38 millimetri o anche un pistone 40 millimetri e il manicotto.

Per il pistone 38mm, avrete bisogno di un sigillo Brembo 38 mm, codice 05.5955.57

Per il pistone 40mm, avrete bisogno di un sigillo Brembo 40mm, codice 05.5955.58

Questa conversione consente ancora l'utilizzo di tutte le altre parti di dimensioni standard che vengono nel kit KC-83017

Ho notato che i pistoncini delle Brembo sono difficili da trovare.
Si fa prima a comprare tutta la pinza nuova.

Continua a cercare perché se li trovi interessano anche a me.

Da quello che ho letto, basterebbe chiedere il kit di ricambio da un ricambista oppure presso un rivenditore di ricambi Renault:

A Brembo slider repair kit is available from Renault dealers (part number 7701205496) for £30+VAT. A piston seal kit is also available (part number?) and complete kits that include everything. Bleed nipples are 10mm and common with most Ford calipers (available from most motor factors).

Chiedi ad un concessionario Renault che abbia anche un grosso magazzino ricambi.

Qui in teoria se non ho capito male, forniscono i pistoncini anche per le pinze posteriori Brembo.

Mi puoi dare il codice?
Li hai comprati da un ricambista multimarca oppure dalla rete d'assistenza Renault?
E hai preso la versione di serie che dovrebbero essere da 36mm o quelli maggiorati da 38 mm o 40mm che dovrebbero migliorare la frenata del 23%?

E soprattutto quanto li hai pagati i 2 pistoncini?
Perché la prossima settimana forse li cambio pure io.

Grazie.

Io ho preso quello da 36 ne ho dovuto cambiare uno... Avevo chiesto in Lotus alla pb racing, hanno pinze usate ma vendono tutta la pinza...e non a poco...fortunatamente zoop mi ha spiegato che quei pistoncini sono identici.
